STRMODE(3)	       FreeBSD Library Functions Manual		    STRMODE(3)

NAME
     strmode --	convert	inode status information into a	symbolic string

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <string.h>

     void
     strmode(mode_t mode, char *bp);

DESCRIPTION
     The strmode() function converts a file mode (the type and permission
     information associated with an inode, see stat(2))	into a symbolic	string
     which is stored in	the location referenced	by bp.	This stored string is
     eleven characters in length plus a	trailing NUL.

     The first character is the	inode type, and	will be	one of the following:

	   -	 regular file
	   b	 block special
	   c	 character special
	   d	 directory
	   l	 symbolic link
	   p	 fifo
	   s	 socket
	   w	 whiteout
	   ?	 unknown inode type

     The next nine characters encode three sets	of permissions,	in three char-
     acters each.  The first three characters are the permissions for the
     owner of the file,	the second three for the group the file	belongs	to,
     and the third for the ``other'', or default, set of users.

     Permission	checking is done as specifically as possible.  If read permis-
     sion is denied to the owner of a file in the first	set of permissions,
     the owner of the file will	not be able to read the	file.  This is true
     even if the owner is in the file's	group and the group permissions	allow
     reading or	the ``other'' permissions allow	reading.

     If	the first character of the three character set is an ``r'', the	file
     is	readable for that set of users;	if a dash ``-'', it is not readable.

     If	the second character of	the three character set	is a ``w'', the	file
     is	writable for that set of users;	if a dash ``-'', it is not writable.

     The third character is the	first of the following characters that apply:

     S	   If the character is part of the owner permissions and the file is
	   not executable or the directory is not searchable by	the owner, and
	   the set-user-id bit is set.

     S	   If the character is part of the group permissions and the file is
	   not executable or the directory is not searchable by	the group, and
	   the set-group-id bit	is set.

     T	   If the character is part of the other permissions and the file is
	   not executable or the directory is not searchable by	others,	and
	   the ``sticky'' (S_ISVTX) bit	is set.

     s	   If the character is part of the owner permissions and the file is
	   executable or the directory searchable by the owner,	and the	set-
	   user-id bit is set.

     s	   If the character is part of the group permissions and the file is
	   executable or the directory searchable by the group,	and the	set-
	   group-id bit	is set.

     t	   If the character is part of the other permissions and the file is
	   executable or the directory searchable by others, and the
	   ``sticky'' (S_ISVTX)	bit is set.

     x	   The file is executable or the directory is searchable.

     -	   None	of the above apply.

     The last character	will always be a space.
