.Sh SYNOPSIS
|
|
.In stdlib.h
|
|
.Sh DESCRIPTION
|
|
The
|
|
.In stdlib.h
|
|
header defines the following types and macros:
|
|
.Bl -enum -offset 4n
|
|
.It
|
|
.Dv NULL
|
|
- an implementation-defined null pointer constant;
|
|
.It
|
|
.Vt size_t
|
|
and
|
|
.Vt wchar_t
|
|
- integer types described in
|
|
.Xr stddef 3 ;
|
|
.It
|
|
.Vt div_t ,
|
|
.Vt ldiv_t ,
|
|
and
|
|
.Vt lldiv_t
|
|
- structures that are returned by the
|
|
.Xr div 3 ,
|
|
.Xr ldiv 3 ,
|
|
and
|
|
.Xr lldiv 3
|
|
functions, respectively;
|
|
.It
|
|
.Dv RAND_MAX
|
|
- a macro which expands to an integer constant
|
|
that is the maximum value returned by the
|
|
.Xr rand 3
|
|
function;
|
|
.It
|
|
.Dv MB_CUR_MAX
|
|
- an integer expression of type
|
|
.Vt size_t
|
|
whose value is the maximum number of bytes in a
|
|
character specified by the current locale; and
|
|
.It
|
|
.Dv EXIT_SUCCESS
|
|
and
|
|
.Dv EXIT_FAILURE
|
|
- macros which expand to integer constants
|
|
suitable for use as an argument to the
|
|
.Xr exit 3
|
|
function.
|
|
.El
|
|
.Pp
|
|
The
|
|
.In stdlib.h
|
|
header also prototypes several important functions such as
|
|
.Xr abort 3 ,
|
|
.Xr atoi 3 ,
|
|
.Xr bsearch 3 ,
|
|
.Xr free 3 ,
|
|
.Xr malloc 3 ,
