ACL_DELETE_PERM(3)       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

       <sys/types.h> <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 (one of ACL_READ, ACL_WRITE, ACL_EXECUTE)
       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;
       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_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)
