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