STDLIB(3)						   BSD 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 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.

NAME

       stdlib.h, stdlib - standard library definitions

SYNOPSIS

       #include <stdlib.h>

DESCRIPTION

       The <stdlib.h> header defines the following macros:

       EXIT_FAILURE    Unsuccessful termination for exit(); evaluates to a non-zero value. See exit(3C).

       EXIT_SUCCESS    Successful termination for exit(); evaluates to 0.

       NULL            Null pointer.

       {RAND_MAX}      Maximum value returned by rand(); at least 32767. See rand(3C).

       {MB_CUR_MAX}    Integer expression whose value is the maximum number of bytes in a character specified by the current locale.

       The following data types are defined through typedef:

       div_t           structure type returned by the div() function

       ldiv_t          structure type returned by the ldiv() function

       lldiv_t         structure type returned by the lldiv() function

       size_t          as described in <stddef.h>

       wchar_t         as described in <stddef.h>

       See div(3C), which covers div(), ldiv(), and lldiv(), and stddef.h(3HEAD).

       In addition, the symbolic names and macros listed below are defined as in <sys/wait.h>, for use in decoding the return value from system().
       See wait.h(3HEAD) and system(3C).
