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