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.
