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.
