ACL_DELETE_PERM(3) BSD Library Functions Manual ACL_DELETE_PERM(3)
NAME
acl_delete_perm -- delete a permission from an ACL permission set
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include <sys/types.h>
#include <sys/acl.h>
int
acl_delete_perm(acl_permset_t permset_d, acl_perm_t perm);
DESCRIPTION
The acl_delete_perm() function deletes the permission contained in the
argument perm from the permission set referred to by the argument
permset_d. An attempt to delete a permission that is not 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_delete_perm() function returns the value 0 if successful; other-
wise 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_delete_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)
