NAME

       acl_set_qualifier - Sets the tag qualifier (UID or GID) on an ACL entry

LIBRARY

       Security Library (libpacl.a)

SYNOPSIS

       #include <sys/acl.h>
       int acl_set_qualifier(	   acl_entry_t entry_d;      void *tag_qualifier_p);

PARAMETERS

       Designates  the	working  storage  internal representation ACL entry to set the tag qualifier in.  Designates the uid or gid to set the tag
       qualifier to.

DESCRIPTION

       NOTE:  This function is based on Draft 13 of the POSIX P1003.6 standard.

       Given an ACL entry, the acl_set_qualifier() function sets the id in the ACL entry.  If the tag type of the given ACL entry is ACL_USER then
       tag_qualifier_p	is  evaluated  as  a  pointer of type *uid_t.  If the tag type of the given ACL entry is ACL_GROUP then tag_qualifier_p is
       evaluated as a pointer of type *gid_t.  Any other ACL tag type results in an error.

RETURN VALUES

       Upon successful completion, the acl_set_qualifier() function returns a value of 0 (zero).  Otherwise, a value of -1 is returned	and  errno
       is set to indicate the error.

ERRORS

       If any of the following conditions occur, the acl_set_qualifier() function sets errno to the corresponding value:

       Argument entry_d does not refer to a valid ACL entry.

       The value of the tag type in ACL entry referred to by entry_d is ACL_USER_OBJ, ACL_GROUP_OBJ, or ACL_OTHER_OBJ.

       The value of the entry in tag_qualifier_p is not valid.	There is not enough memory available  to allocate the ACL uid/gid storage.

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 con-
			straints.
