Detailed Description

OCCT-Light: core public API.

Status codes, thread-local error reporting, runtime lifecycle, version queries. The base every other OCCT-Light module depends on.

See also: ../../docs/design/ABI_PATTERNS.md for ABI conventions.; ../../docs/design/ARCHITECTURE.md for the layered design.

Macro Definition Documentation

◆ OCCTL_ABI_VERSION

#define OCCTL_ABI_VERSION 1

ABI version. Bumped only on hard breakage. Independent of SemVer.

Consumers may compare this against occtl_runtime_abi_version at load time and refuse to proceed on mismatch.

◆ OCCTL_ANGLE_1_DEG_RAD

#define OCCTL_ANGLE_1_DEG_RAD OCCTL_RAD_PER_DEG

1 degree in radians.

◆ OCCTL_ANGLE_20_DEG_RAD

#define OCCTL_ANGLE_20_DEG_RAD (20.0 * OCCTL_RAD_PER_DEG)

20 degrees in radians.

◆ OCCTL_ANGLE_30_DEG_RAD

#define OCCTL_ANGLE_30_DEG_RAD (30.0 * OCCTL_RAD_PER_DEG)

30 degrees in radians.

◆ OCCTL_ANGLE_5_DEG_RAD

#define OCCTL_ANGLE_5_DEG_RAD (5.0 * OCCTL_RAD_PER_DEG)

5 degrees in radians.

◆ OCCTL_ANGLE_90_DEG_RAD

#define OCCTL_ANGLE_90_DEG_RAD OCCTL_PI_OVER_TWO

90 degrees in radians.

◆ OCCTL_API

#define OCCTL_API

Symbol export macro. Applied to every public function declaration.

Building shared on Windows : __declspec(dllexport)
Consuming shared on Windows : __declspec(dllimport)
Building or consuming static: empty
All non-Windows platforms : __attribute__((visibility("default")))

◆ OCCTL_FAILED

#define OCCTL_FAILED ( status ) ((status) != OCCTL_OK)

Returns: non-zero if status indicates failure.

◆ OCCTL_PI

#define OCCTL_PI 3.14159265358979323846

Mathematical constants shared across public C headers.

These macros are used by options INIT defaults so callers and bindings can refer to one named source of truth instead of repeating magic literals.

◆ OCCTL_PI_OVER_TWO

#define OCCTL_PI_OVER_TWO (0.5 * OCCTL_PI)

OCCTL_PI / 2.

◆ OCCTL_RAD_PER_DEG

#define OCCTL_RAD_PER_DEG (OCCTL_PI / 180.0)

Radians in one degree.

◆ OCCTL_RUNTIME_INIT_INFO_INIT

#define OCCTL_RUNTIME_INIT_INFO_INIT {OCCTL_RUNTIME_INIT_INFO_VERSION_1, NULL}

Static initializer for occtl_runtime_init_info_t.

◆ OCCTL_RUNTIME_INIT_INFO_VERSION_1

#define OCCTL_RUNTIME_INIT_INFO_VERSION_1 1u

Init info versioning constant. New fields are appended under new version constants in future releases.

◆ OCCTL_SUCCEEDED

#define OCCTL_SUCCEEDED ( status ) ((status) == OCCTL_OK)

Returns: non-zero if status indicates success.

◆ OCCTL_TWO_PI

#define OCCTL_TWO_PI (2.0 * OCCTL_PI)

2 * OCCTL_PI.

◆ OCCTL_UID_INVALID

#define OCCTL_UID_INVALID ((occtl_uid_t){0})

Invalid UID sentinel. Equivalent to (occtl_uid_t){0}.

Defined as a C99 compound literal in C and as a C++ braced initialiser in C++; this avoids compound-literal warnings on MSVC and pedantic C++ modes.

◆ OCCTL_UID_WIRE_SIZE

#define OCCTL_UID_WIRE_SIZE 16u

Number of bytes in the wire-format encoding of an occtl_uid_t.

The wire format is a fixed-width opaque blob; do not parse it. The top 8 bytes carry the current 64-bit packed identity in big-endian order; the bottom 8 bytes are reserved (always zero today) so that future widening of the kind tag or counter field can re-key existing stored UIDs without breaking persistence.

◆ OCCTL_VERSION_MAJOR

#define OCCTL_VERSION_MAJOR 0

Library SemVer. Refer at compile time; for runtime checks use occtl_runtime_version.

These are defined by the build system. Defaults are zero-or-fallback if a non-CMake build forgets to set them.

Typedef Documentation

◆ occtl_error_t

typedef struct occtl_error occtl_error_t

Thread-local description of the most recent failure.

Populated automatically when any public function returns a non-OK status. Read it with occtl_error_last; clear it with occtl_error_clear.

The message pointer is library-owned and is only valid until the next OCCT-Light call on this thread. Copy it out if you need to retain it.

◆ occtl_node_kind_t

typedef enum occtl_node_kind occtl_node_kind_t

Node kind discriminator.

Applies to occtl_node_id_t, occtl_uid_t, and occtl_ref_id_t payloads. Values are stable forever; new kinds are appended before OCCTL_NODE_KIND_RESERVED_FUTURE. OCCTL_KIND_INVALID = 0 is the zero sentinel so calloc / memset-zero IDs are naturally invalid.

◆ occtl_ref_kind_t

typedef enum occtl_ref_kind occtl_ref_kind_t

Reference-entry kind discriminator for occtl_ref_id_t.

Reference entries express usages of a node (e.g. a Face used inside a Shell). Zero is reserved as the universal invalid sentinel.

◆ occtl_rep_id_t

typedef struct occtl_rep_id occtl_rep_id_t

Identity of a representation (geometry / mesh data) in the graph.

The all-zero value (OCCTL_REP_ID_INVALID) is the invalid sentinel.

◆ occtl_rep_kind_t

typedef enum occtl_rep_kind occtl_rep_kind_t

Representation kind discriminator for occtl_rep_id_t.

Representations are the data attached to a node — geometry (Surface, Curve3D, Curve2D) or mesh (Triangulation, Polygon3D, Polygon2D, PolygonOnTri). Unrecognised representation kinds are surfaced as OCCTL_REP_KIND_INVALID by the current ABI.

◆ occtl_runtime_init_info_t

typedef struct occtl_runtime_init_info occtl_runtime_init_info_t

Options for occtl_runtime_init.

Construct with OCCTL_RUNTIME_INIT_INFO_INIT or by zero-initialising and setting struct_version explicitly.

◆ occtl_status_t

typedef enum occtl_status occtl_status_t

Status code returned by every OCCT-Light public function.

OCCTL_OK is 0; idiomatic checks if (occtl_xxx(...) != OCCTL_OK) and if (s) goto fail; both work.

The numeric values listed here are stable forever; new values may be appended in future versions. Consumers that switch on the code must default unknown values to a generic-failure code path.

◆ occtl_uid_t

typedef struct occtl_uid occtl_uid_t

Persistent unique identity of a graph entity.

Survives compact and most node removals, unlike occtl_node_id_t which is session-local. The all-zero value (OCCTL_UID_INVALID) is the invalid sentinel — compare with uid.bits == 0.

To query the kind of a UID, call occtl_graph_uid_kind() (declared in occtl_topo.h when OCCTL_HAS_TOPO is defined).

Enumeration Type Documentation

◆ occtl_node_kind

enum occtl_node_kind

Node kind discriminator.

Applies to occtl_node_id_t, occtl_uid_t, and occtl_ref_id_t payloads. Values are stable forever; new kinds are appended before OCCTL_NODE_KIND_RESERVED_FUTURE. OCCTL_KIND_INVALID = 0 is the zero sentinel so calloc / memset-zero IDs are naturally invalid.

Function Documentation

◆ occtl_error_clear()

void occtl_error_clear ( void )

Clears the thread-local last error.

Calling this is optional — every public function that returns OCCTL_OK already clears the slot. Use it explicitly when you want to assert "no prior failure" before a sequence of calls.

\par Thread Safety Yes (per-thread).

See also: occtl_error_last

◆ occtl_error_last()

const occtl_error_t * occtl_error_last ( void )

Returns the thread-local last error.

Always returns a non-NULL pointer; an all-zero status field means "no error pending on this thread."

Returns: Borrowed pointer to thread-local storage. Valid until the next OCCT-Light call on this thread.

\par Thread Safety Yes (per-thread).

See also: occtl_error_clear, occtl_status_to_string

◆ occtl_runtime_abi_version()

uint32_t occtl_runtime_abi_version ( void )

Returns the runtime ABI version.

Compare to OCCTL_ABI_VERSION at load time and refuse to load if they differ — that protects against mixing a newer header with an older binary.

Returns: The ABI version compiled into this build.

\par Thread Safety Yes.

See also: occtl_runtime_version

◆ occtl_runtime_init()

occtl_status_t occtl_runtime_init ( const occtl_runtime_init_info_t * info )

Initialises the OCCT-Light runtime.

Calling this is optional: every entry point lazy-initialises with defaults if needed.

Calling more than once is a programming error; subsequent calls return OCCTL_INVALID_ARGUMENT and have no effect.

Parameters

[in] info Borrows it. Optional. NULL = use defaults. When non-NULL, info->struct_version must be a recognised value.

Return values

OCCTL_OK	On success or if defaults already applied.
OCCTL_VERSION_MISMATCH	`info->struct_version` is unsupported.
OCCTL_INVALID_ARGUMENT	Already initialised, or an invalid combination.

\par Thread Safety No (call before any other thread issues OCCT-Light calls).

See also: occtl_runtime_shutdown, occtl_runtime_version

◆ occtl_runtime_init_info_init()

occtl_status_t occtl_runtime_init_info_init ( occtl_runtime_init_info_t * info )

Initialises an occtl_runtime_init_info_t to the default values.

Equivalent to #OCCTL_RUNTIME_INIT_INFO_INIT but callable from binding languages that cannot use C macros.

Parameters

[out] info Owns it (caller-allocated). Must be non-NULL.

Return values

OCCTL_OK	On success.
OCCTL_INVALID_ARGUMENT	`info` is NULL.

\par Thread Safety Yes.

See also: occtl_runtime_init

◆ occtl_runtime_occt_version()

const char * occtl_runtime_occt_version ( void )

Returns the OCCT version OCCT-Light was built against.

Diagnostic only; not part of OCCT-Light's ABI promise.

Returns: Borrowed pointer to a NUL-terminated UTF-8 string of the form "7.x.y". Library-owned, valid for the process lifetime.

\par Thread Safety Yes.

See also: occtl_runtime_version

◆ occtl_runtime_shutdown()

void occtl_runtime_shutdown ( void )

Releases process-wide runtime state allocated by occtl_runtime_init.

After this returns, OCCT-Light entry points may still be called — they will lazy-initialise again with defaults. Call this only at process teardown when you want a clean state.

\par Thread Safety No (no other thread may issue OCCT-Light calls during shutdown).

See also: occtl_runtime_init

◆ occtl_runtime_version()

void occtl_runtime_version	(	uint32_t *	out_major,
		uint32_t *	out_minor,
		uint32_t *	out_patch
	)

Returns the runtime SemVer.

Out parameters may individually be NULL if the caller doesn't want a particular field; pass NULL for all three to get a no-op call.

Parameters

[out]	out_major	Borrows it. Optional.
[out]	out_minor	Borrows it. Optional.
[out]	out_patch	Borrows it. Optional.

\par Thread Safety Yes.

See also: OCCTL_VERSION_MAJOR, occtl_runtime_abi_version

◆ occtl_status_to_string()

const char * occtl_status_to_string ( occtl_status_t status )

Returns a human-readable name for a status code.

Useful for logging. The string is library-owned and valid for the lifetime of the process; do not free it.

Parameters

[in] status A status code.

Returns: Borrowed pointer to a NUL-terminated UTF-8 string. Returns "OCCTL_UNKNOWN" if status is not a recognised value.

\par Thread Safety Yes.

See also: occtl_error_last

◆ occtl_uid_equal()

int32_t occtl_uid_equal	(	occtl_uid_t	a,
		occtl_uid_t	b
	)

Tests two UIDs for equality.

Parameters

[in]	a	First UID.
[in]	b	Second UID.

Return values

1	UIDs are equal.
0	UIDs differ.

\par Thread Safety Yes.

See also: occtl_uid_to_bytes, occtl_uid_from_bytes

◆ occtl_uid_from_bytes()

occtl_status_t occtl_uid_from_bytes	(	const uint8_t *	in_bytes,
		occtl_uid_t *	out_uid
	)

Decodes a 16-byte wire-format UID back into an occtl_uid_t.

Rejects payloads whose reserved bytes are non-zero (returns OCCTL_FORMAT_ERROR) — those signal a future wider encoding that this build does not understand. An all-zero input returns OCCTL_UID_INVALID with OCCTL_OK.

Parameters

[in]	in_bytes	Borrows it. Must point to a readable buffer of at least OCCTL_UID_WIRE_SIZE bytes.
[out]	out_uid	Borrows it. Must be non-NULL.

Return values

OCCTL_OK	On success.
OCCTL_INVALID_ARGUMENT	`in_bytes` or `out_uid` is NULL.
OCCTL_FORMAT_ERROR	Reserved bytes are non-zero.

\par Thread Safety Yes.

See also: occtl_uid_to_bytes

◆ occtl_uid_to_bytes()

occtl_status_t occtl_uid_to_bytes	(	occtl_uid_t	uid,
		uint8_t *	out_bytes
	)

Encodes a UID into its 16-byte wire format.

Round-trips losslessly through occtl_uid_from_bytes for any valid or invalid UID. Byte order is fixed at big-endian and stable across future ABI versions.

Parameters

[in]	uid	UID to encode (may be OCCTL_UID_INVALID).
[out]	out_bytes	Borrows it. Must point to a writable buffer of at least OCCTL_UID_WIRE_SIZE bytes.

Return values

OCCTL_OK	On success.
OCCTL_INVALID_ARGUMENT	`out_bytes` is NULL.

\par Thread Safety Yes.
