ACL_SET_QUALIFIER(3)     BSD Library Functions Manual     ACL_SET_QUALIFIER(3)

NAME
     acl_set_qualifier -- set ACL tag qualifier

LIBRARY
     Standard C Library (libc, -lc)

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

     int
     acl_set_qualifier(acl_entry_t entry_d, const void *tag_qualifier_p);

DESCRIPTION
     The acl_set_qualifier() function is a POSIX.1e call that sets the qualifier of the tag for the ACL
     entry entry_d to the value referred to by tag_qualifier_p.

     The tag type of the ACL entry, as previously set with acl_set_tag_type(3), must be either
     ACL_EXTENDED_ALLOW or ACL_EXTENDED_DENY, and tag_qualifier_p should be a pointer to a global unique
     identifier (of type guid_t).

RETURN VALUES
     The acl_set_qualifier() 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
     The acl_set_qualifier() function fails if:

     [EINVAL]           Argument entry_d is not a valid descriptor for an ACL entry.  The tag type of the
                        ACL entry entry_d is not ACL_EXTENDED_ALLOW or ACL_EXTENDED_DENY.  The value pointed
                        to by tag_qualifier_p is not valid.

     [ENOMEM]           The value to be returned requires more memory than is allowed by the hardware or
                        system-imposed memory management constraints.

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