  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.
