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). SEE ALSO
stddef(3), types(3), unistd(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. BSD
April 10, 2011 BSD

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).
