.Os "Linux ACL"

.Sh NAME

.Nm acl_copy_int

.Nd copy an ACL from external to internal representation

.Sh LIBRARY

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

.Sh SYNOPSIS

.In sys/types.h

.In sys/acl.h

.Ft acl_t

.Fn acl_copy_int "const void *buf_p"

.Sh DESCRIPTION

The

.Fn acl_copy_int

function copies an exportable, contiguous, persistent form of an ACL, pointed to by

.Va buf_p ,

to the internal representation.

.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_copy_int

as an argument.

.Sh RETURN VALUE

Upon success,

the

.Fn acl_copy_int

function returns a pointer that references the ACL in 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_copy_int

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 buffer pointed to by the argument

.Va buf_p

does not contain a valid external form ACL.

.It Bq Er ENOMEM

The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
