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.
