NAME
stdlib - standard library definitions
SYNOPSIS
#include <stdlib.h>
DESCRIPTION
The <stdlib.h> header defines the following types and macros:
1. NULL - an implementation-defined null pointer constant;
2. size_t and wchar_t - integer types described in stddef(3);
3. div_t, ldiv_t, and lldiv_t - structures that are returned by the
div(3), ldiv(3), and lldiv(3) functions, respectively;
4. RAND_MAX - a macro which expands to an integer constant that is
the maximum value returned by the rand(3) function;
5. MB_CUR_MAX - an integer expression of type size_t whose value is
the maximum number of bytes in a character specified by the
current locale; and
6. EXIT_SUCCESS and EXIT_FAILURE - macros which expand to integer
constants suitable for use as an argument to the exit(3)
function.
The <stdlib.h> header also prototypes several important functions such as
abort(3), atoi(3), bsearch(3), free(3), malloc(3), and strtol(3).
