xrealloc () - get more memory or bust
xrealloc () uses realloc ()
my_memory = xrealloc (my_memory, 42);
/ * my_memory gets (perhaps new) address of 42 chars * /
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.
if ((ptr
= realloc (ptr
, (unsigned)n
)) == 0)
error ("virtual memory exceeded");
