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).
