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).

STANDARDS

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

HISTORY

     In the current form the <stdlib.h> header was introduced in NetBSD 0.8.
