CFP_REALLOCPROC callback function (fontsub.h)
Client-provided callback function, used by CreateFontPackage and MergeFontPackage to reallocate memory when the size of an allocated buffer needs to change.
Syntax
CFP_REALLOCPROC CfpReallocproc;
void * CfpReallocproc(
void *unnamedParam1,
size_t unnamedParam2
)
{...}
Parameters
unnamedParam1
Pointer to previously allocated memory block.
unnamedParam2
New size in bytes.
Return value
Returns a void pointer to the reallocated (and possibly moved) memory block. The return value should be NULL if the size is zero and the memblock argument is not NULL, or if there is not enough available memory to expand the block to the given size. In the first case, the original block should be freed. In the second, the original block should be unchanged.
Remarks
realloc conforms to this type; the application can either use realloc or a more specialized function for memory reallocation. Whatever function is chosen, there must also be appropriate functions for initial allocation and to free this memory.
