|
||
|
|
.Sh LIBRARY
|
||
|
|
Linux Access Control Lists library (libacl, \-lacl).
|
||
|
|
.Sh SYNOPSIS
|
||
|
|
.In sys/types.h
|
||
|
|
.In sys/acl.h
|
||
|
|
.Ft int
|
||
|
|
.Fn acl_set_qualifier "acl_entry_t entry_d" "const void *qualifier_p"
|
||
|
|
.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Fn acl_set_qualifier
|
||
|
|
function sets the qualifier of the ACL entry indicated by the argument
|
||
|
|
.Va entry_d
|
||
|
|
to the value referred to by the argument
|
||
|
|
.Va qualifier_p .
|
||
|
|
If the value of the tag type in the ACL entry referred to by
|
||
|
|
.Va entry_d
|
||
|
|
is ACL_USER, then the value referred to by
|
||
|
|
.Va qualifier_p
|
||
|
|
shall be of type
|
||
|
|
.Va uid_t .
|
||
|
|
If the value of the tag type in the ACL entry referred to by
|
||
|
|
.Va entry_d
|
||
|
|
is ACL_GROUP, then the value referred to by
|
||
|
|
.Va qualifier_p
|
||
|
|
shall be of type
|
||
|
|
.Va gid_t .
|
||
|
|
If the value of the tag type in the ACL entry referred to by
|
||
|
|
.Va entry_d
|
||
|
|
is a tag type for which a qualifier is not supported,
|
||
|
|
.Fn acl_set_qualifier
|
||
|
|
returns an error.
|
||
|
|
.Pp
|
||
|
|
Any ACL entry descriptors that refer to the entry referred to by
|
||
|
|
.Va entry_d
|
||
|
|
continue to refer to that entry. This function may cause memory to be
|
||
|
|
allocated. The caller should free any releasable memory, when the ACL
|
||
|
|
is no longer required, by calling
|
||
|
|
.Fn acl_free
|
||
|
|
with a pointer to the ACL as argument.
|
||
|
|
.Sh RETURN VALUE
|

|
||
|
|
.Sh ERRORS
|
||

If any of the following conditions occur, the
|
||
|
|
.Fn acl_set_qualifier
|
||
|
|
function returns
|
||
|
|
.Li -1
|
