ACL_DELETE_ENTRY(3)     NetBSD Library Functions Manual    ACL_DELETE_ENTRY(3)


NAME

     acl_delete_entry, acl_delete_entry_np -- delete an ACL entry from an ACL


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_delete_entry(acl_t acl, acl_entry_t entry_d);

     int
     acl_delete_entry_np(acl_t acl, int index);


DESCRIPTION

     The acl_delete_entry() function is a POSIX.1e call that removes the ACL
     entry entry_d from ACL acl.  The acl_delete_entry_np() function is a non-
     portable version that removes the ACL entry at position index from ACL
     acl.  Positions are numbered starting from zero, i.e. calling
     acl_delete_entry_np() with index argument equal to zero will remove the
     first ACL entry.


RETURN VALUES

     The acl_delete_entry() 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

     The acl_delete_entry() function fails if:

     [EINVAL]           Argument acl does not point to a valid ACL.  Argument
                        entry_d is not a valid descriptor for an ACL entry in
                        acl.  Argument index is out of bounds.

STANDARDS

     POSIX.1e is described in IEEE POSIX.1e draft 17.


HISTORY

     POSIX.1e support was introduced in FreeBSD 4.0.  The acl_delete_entry()
