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; 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)
