.Dt ACL_INIT 3

.Os "Linux ACL"

.Sh NAME

.Nm acl_init

.Nd initialize ACL working storage

.Sh LIBRARY

Linux Access Control Lists library (libacl, \-lacl).

.Sh SYNOPSIS

.In sys/types.h

.In sys/acl.h

.Ft acl_t

.Fn acl_init "int count"

.Sh DESCRIPTION

The

.Fn acl_init

function allocates and initializes the working storage for an ACL of at least

.Va count

ACL entries.  The ACL created initially contains no ACL entries.

A pointer to the working storage is returned.

.Pp

This function may cause memory to be allocated.  The caller should free any

releasable memory, when the new ACL is no longer required, by calling

.Xr acl_free 3

with the

.Va (void*)acl_t

returned by

.Fn acl_init

as an argument.

.Sh RETURN VALUE

On success, this function returns a pointer to the

working storage.  On error, a value of

.Li (acl_t)NULL

is returned, and

.Va errno

is set appropriately.

.Sh ERRORS

If any of the following conditions occur, the

.Fn acl_init

function returns a value of

.Li (acl_t)NULL

and sets

.Va errno

to the corresponding value:

.Bl -tag -width Er

.It Bq Er EINVAL

The value of count is less than zero.

.It Bq Er ENOMEM

The

.Va acl_t

to be returned requires more memory than is allowed by the hardware or

system-imposed memory management constraints.

.El

.Sh STANDARDS

IEEE Std 1003.1e draft 17 (\(lqPOSIX.1e\(rq, abandoned)
