STDLIB(3)               NetBSD Library Functions Manual              STDLIB(3)


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 cur-
              rent locale; and

         6.   EXIT_SUCCESS and EXIT_FAILURE - macros which expand to integer
              constants suitable for use as an argument to the exit(3) func-
              tion.

     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.
