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