Tcl_Alloc, Tcl_Free, Tcl_Realloc - allocate or free heap memory
These procedures provide a platform and compiler independent interface
for memory allocation. Programs that need to transfer ownership of
memory blocks between Tcl and other modules should use these routines
rather than the native malloc() and free() routines
provided by the C run-time library.
- int size (in)
Size in bytes of the memory block to allocate.
- char *ptr (in)
Pointer to memory block to free or realloc.
Tcl_Alloc returns a pointer to a block of at least size
bytes suitably aligned for any use.
Tcl_Free makes the space referred to by ptr available for
Tcl_Realloc changes the size of the block pointed to by
ptr to size bytes and returns a pointer to the new block.
The contents will be unchanged up to the lesser of the new and old
sizes. The returned location may be different from ptr.
