NAME
acl_add_perm — add
a permission to an ACL permission set
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include
<sys/types.h>
#include <sys/acl.h>
int
acl_add_perm(acl_permset_t
permset_d, acl_perm_t
perm);
DESCRIPTION
The
acl_add_perm()
function adds the permission contained in the argument
perm (one of ACL_READ, ACL_WRITE, ACL_EXECUTE) to the
permission set referred to by the argument permset_d.
An attempt to add a permission that is already contained in the permission
set is not considered an error.
Any existing descriptors that refer to permset_d continue to refer to that permission set.
RETURN VALUE
The acl_add_perm() function returns the
value 0 if successful; otherwise the value -1 is returned and
the global variable errno is set to indicate the
error.
ERRORS
If any of the following conditions occur, the
acl_add_perm() function returns
-1 and sets errno to the
corresponding value:
- [
EINVAL] - The argument permset_d is not a valid descriptor for
a permission set within an ACL entry.
The argument perm does not contain a valid acl_perm_t value.
STANDARDS
IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned)
