ACL_SET_QUALIFIER(3)       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.

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_USER or ACL_GROUP.  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.
