Detailed Description

Internal helpers for accessing context state from library subsystems.

These declarations are for internal use only and must not be included by external code.

Definition in file sbgl_context_internal.h.

Function Documentation

sbgl_GetContextArena()

SblArena * sbgl_GetContextArena

(

sbgl_Context *

ctx

)

Retrieves the persistent arena associated with a context.

Subsystems that need a lifetime-bound allocation region (e.g., the voxel engine) use this arena instead of malloc to remain consistent with the library's memory model.

Parameters

ctx	The engine context.

Returns

Pointer to the context's persistent arena, or NULL if the context is invalid.
