stdlib -- standard library definitions
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).

As described here, the <stdlib.h> header conforms to ISO/IEC 9899:1999 (``ISO C99'') and
IEEE Std 1003.1-2001 (``POSIX.1'').
In the current form the <stdlib.h> header was introduced in NetBSD 0.8.
