|
.Sh SYNOPSIS
|
|
.In sys/types.h
|
|
.In sys/acl.h
|
|
.Ft int
|
|
.Fn acl_get_entry "acl_t acl" "int entry_id" "acl_entry_t *entry_p"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn acl_get_entry
|
|
function
|
|
is a POSIX.1e call that retrieves a descriptor for an ACL entry
|
|
specified by the argument
|
|
.Fa entry_d
|
|
within the ACL indicated by the argument
|
|
.Fa acl .
|
|
.Pp
|
|
If the value of
|
|
.Fa entry_id
|
|
is
|
|
.Dv ACL_FIRST_ENTRY ,
|
|
then the function will return in
|
|
.Fa entry_p
|
|
a descriptor for the first ACL entry within
|
|
.Fa acl .
|
|
If a call is made to
|
|
.Fn acl_get_entry
|
|
with
|
|
.Fa entry_id
|
|
set to
|
|
.Dv ACL_NEXT_ENTRY
|
|
when there has not been either an initial successful call to
|
|
.Fn acl_get_entry ,
|
|
or a previous successful call to
|
|
.Fn acl_create_entry ,
|
|
.Fn acl_delete_entry ,
|
|
.Fn acl_dup ,
|
|
.Fn acl_from_text ,
|
|
.Fn acl_get_fd ,
|
|
.Fn acl_get_file ,
|
|
.Fn acl_set_fd ,
|
|
.Fn acl_set_file ,
|
|
or
|
|
.Fn acl_valid ,
|
|
then the result is unspecified.
|
|
.Sh RETURN VALUES
|
|
If the
|
|
.Fn acl_get_entry
|
|
function successfully obtains an ACL entry, a value of 1 is returned.
|
|
If the ACL has no ACL entries, the
|
|
.Fn acl_get_entry
|
|
returns a value of 0.
|
|
If the value of
|
|
.Fa entry_id
|
|
is
|
|
.Dv ACL_NEXT_ENTRY
|
|
and the last ACL entry in the ACL has already been returned by a
|
|
previous call to
|
|
.Fn acl_get_entry ,
|
|
a value of 0 will be returned until a successful call with
|
|
.Fa entry_id
|
|
of
|
|
.Dv ACL_FIRST_ENTRY
|
|
is made.
|
|
Otherwise, a value of -1 will be returned and
|
|
the global variable
|
|
.Va errno
|
|
will be set to indicate the error.
|
|
.Sh ERRORS
|
