void HeapFreeIndir (HANDLE *HandlePtr);

Frees a heap block given a pointer to it.

HeapFreeIndir is like HeapFree except you pass the address of a variable which keeps the block handle instead of the handle itself. If the handle that HandlePtr points to is not H_NULL, then it frees that handle and sets the handle variable that is pointed to by HandlePtr to H_NULL.
Maybe this sounds a bit confusing to you. In fact, doing

    HeapFreeIndir (&handle);    // The ampersand ('&') is important

works exactly the same as

    if (handle) HeapFree (handle);
    handle = H_NULL;

Note: In releases of TIGCCLIB prior to 2.2, the information about this routine was quite misleading or even wrong.
