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 quali-
     fier 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; oth-
     erwise 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 man-
                        agement constraints.
