26 xrealloc () - get more memory or bust
28 xrealloc () uses realloc ()
32 my_memory = xrealloc (my_memory, 42);
33 / * my_memory gets (perhaps new) address of 42 chars * /
37 Use xrealloc () as an "error-free" realloc ().It does almost the same
38 job. When it cannot honour your request for memory it BOMBS your
39 program with a "virtual memory exceeded" message. Realloc() returns
40 NULL and does not bomb your program.
56 #define error as_fatal
65 if ((ptr = realloc (ptr, (unsigned)n)) == 0)
66 error ("virtual memory exceeded");
