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)
