Tcl_Alloc(3) Tcl Library Procedures 7.5
Tcl_Alloc, Tcl_Free, Tcl_Realloc - allocate or free heap
int size (in) Size in bytes of the memory block
char *ptr (in) Pointer to memory block to free or
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
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.
