21 NAME
22 xmalloc() - get memory or bust
23 INDEX
24 xmalloc() uses malloc()
25
26 SYNOPSIS
27 char * my_memory;
28
29 my_memory = xmalloc(42); / * my_memory gets address of 42 chars * /
30
31 DESCRIPTION
32
33 Use xmalloc() as an "error-free" malloc(). It does almost the same job.
34 When it cannot honour your request for memory it BOMBS your program
35 with a "virtual memory exceeded" message. Malloc() returns NULL and
36 does not bomb your program.
