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

NAME

     acl_set_qualifier -- set the qualifier of an ACL entry

LIBRARY

     Linux Access Control Lists library (libacl, -lacl).

SYNOPSIS

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

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

DESCRIPTION

     The acl_set_qualifier() function sets the qualifier of the ACL entry indicated by the argument entry_d to the value referred to by the argu-
     ment qualifier_p.	If the value of the tag type in the ACL entry referred to by entry_d is ACL_USER, then the value referred to by
     qualifier_p shall be of type uid_t.  If the value of the tag type in the ACL entry referred to by entry_d is ACL_GROUP, then the value
     referred to by qualifier_p shall be of type gid_t.  If the value of the tag type in the ACL entry referred to by entry_d is a tag type for
     which a qualifier is not supported, acl_set_qualifier() returns an error.

     Any ACL entry descriptors that refer to the entry referred to by entry_d continue to refer to that entry. This function may cause memory to
     be allocated. The caller should free any releasable memory, when the ACL is no longer required, by calling acl_free() with a pointer to the
     ACL as argument.

RETURN VALUE

     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

     If any of the following conditions occur, the acl_set_qualifier() function returns -1 and sets errno to the corresponding value:

     [EINVAL]		The argument entry_d is not a valid descriptor for an ACL entry.

			The value of the tag type in the ACL entry referenced by the argument entry_d is neither ACL_USER nor ACL_GROUP.

			The value pointed to by the argument qualifier_p is not valid.

     [ENOMEM]		The acl_set_qualifier() function is unable to allocate the memory required for the ACL qualifier.

STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)
