Detailed Description
Specifies custom memory-allocation functions.
This section describes the function and types that enable you to specify custom memory-allocation functions that the HOOPS Exchange Library uses in place of the standard malloc
and free
functions.
Typedef Documentation
◆ A3DCallbackMemoryAlloc
typedef A3DPtr(* A3DCallbackMemoryAlloc) (size_t) |
A callback function the HOOPS Exchange Library invokes to allocate memory.
- Version
- 2.0
◆ A3DCallbackMemoryFree
A callback function the HOOPS Exchange Library invokes to free memory.
- Version
- 2.0
◆ PFA3DDllSetCallbacksMemory
typedef A3DStatus( * PFA3DDllSetCallbacksMemory) (A3DCallbackMemoryAlloc, A3DCallbackMemoryFree) |
Specifies custom memory-allocation functions This function specifies callback functions the HOOPS Exchange Library uses for memory allocation and and deallocation.
If this function is not called, the standard malloc
and free
functions are used for memory allocation and deallocation.

- A3Dvoid my_free(A3DPtr ptr) { if (ptr) free(ptr); }A3DInt32 iErr = A3D_SUCCESS;A3DInt32 iMajorVersion,iMinorVersion = 0;iErr = A3DDllGetVersion( &iMajorVersion, &iMinorVersion );iErr = A3DDllInitialize( A3D_DLL_MAJORVERSION, A3D_DLL_MAJORVERSION );if ( iErr == A3D_SUCCESS ){iErr = A3DDllSetCallbacksMemory( my_alloc , my_free );iErr = A3DDllTerminate();}
