25 xrealloc () - get more memory or bust
27 xrealloc () uses realloc ()
31 my_memory = xrealloc (my_memory, 42);
32 / * my_memory gets (perhaps new) address of 42 chars * /
36 Use xrealloc () as an "error-free" realloc ().It does almost the same
37 job. When it cannot honour your request for memory it BOMBS your
38 program with a "virtual memory exceeded" message. Realloc() returns
39 NULL and does not bomb your program.
