ACL_SET_TAG_TYPE(3)					   BSD Library Functions Manual 				       ACL_SET_TAG_TYPE(3)

NAME

     acl_set_tag_type -- set the tag type of an ACL entry

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

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

     int
     acl_set_tag_type(acl_entry_t entry_d, acl_tag_t tag_type);

DESCRIPTION

     The acl_set_tag_type() function is a POSIX.1e call that sets the ACL tag type of ACL entry entry_d to the value of tag_type.

     Valid values are:

	ACL_USER_OBJ	 Permissions apply to file owner
	ACL_USER	 Permissions apply to additional user specified by qualifier
	ACL_GROUP_OBJ	 Permissions apply to file group
	ACL_GROUP	 Permissions apply to additional group specified by qualifier
	ACL_MASK	 Permissions specify mask
	ACL_OTHER	 Permissions apply to other
	ACL_OTHER_OBJ	 Same as ACL_OTHER
	ACL_EVERYONE	 Permissions apply to everyone@

     Calling acl_set_tag_type() with tag_type equal to ACL_MASK, ACL_OTHER or ACL_OTHER_OBJ brands the ACL as POSIX.1e.  Calling it with
     ACL_EVERYONE brands the ACL as NFSv4.

RETURN VALUES

     The acl_set_tag_type() 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_tag_type() function fails if:

     [EINVAL]		Argument entry_d is not a valid descriptor for an ACL entry.  Argument tag_type is not a valid ACL tag type.  ACL is
			already branded differently.

STANDARDS

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

HISTORY

     POSIX.1e support was introduced in FreeBSD 4.0.  The acl_set_tag_type() function was added in FreeBSD 5.0.

AUTHORS

     The acl_set_tag_type() function was written by Chris D. Faulhaber <jedgar@fxp.org>.

ACL_GET_QUALIFIER(3)					   BSD Library Functions Manual 				      ACL_GET_QUALIFIER(3)

NAME

     acl_get_qualifier -- retrieve the qualifier from an ACL entry

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

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

     void *
     acl_get_qualifier(acl_entry_t entry_d);

DESCRIPTION

     The acl_get_qualifier() function is a POSIX.1e call that retrieves the qualifier of the tag for the ACL entry indicated by the argument
     entry_d into working storage and returns a pointer to that storage.

     If the value of the tag type in the ACL entry referred to by entry_d is ACL_EXTENDED_ALLOW or ACL_EXTENDED_DENY The value returned by
     acl_get_qualifier() will be a pointer to type guid_t.

     If the value of the tag type in the ACL entry referred to by entry_d is ACL_UNDEFINED_TAG, a tag type specified by POSIX.1e but not supported
     or an implementation-defined value for which a qualifier is not supported, then acl_get_qualifier() will return a value of (void *)NULL and
     the function will fail.

     This function may cause memory to be allocated.  The caller should free any releasable memory, when the new qualifier is no longer required,
     by calling acl_free() with void * as the argument.

RETURN VALUES

     The acl_get_qualifier() function returns a pointer to the allocated storage if successful; otherwise a NULL pointer is returned and the
     global variable errno is set to indicate the error.

ERRORS

     The acl_get_qualifier() fails if:

     [EINVAL]		Argument entry_d does not point to a valid descriptor for an ACL entry.  The value of the tag type in the ACL entry refer-
			enced by argument entry_d is not ACL_EXTENDED_ALLOW or ACL_EXTENDED_DENY.

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