SETMODE(3)	       FreeBSD Library Functions Manual		    SETMODE(3)

NAME
     getmode, setmode -- modify	mode bits

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <unistd.h>

     mode_t
     getmode(const void	*set, mode_t mode);

     void *
     setmode(const char	*mode_str);

DESCRIPTION
     The getmode() function returns a copy of the file permission bits mode as
     altered by	the values pointed to by set.  While only the mode bits	are
     altered, other parts of the file mode may be examined.

     The setmode() function takes an absolute (octal) or symbolic value, as
     described in chmod(1), as an argument and returns a pointer to mode val-
     ues to be supplied	to getmode().  Because some of the symbolic values are
     relative to the file creation mask, setmode() may call umask(2).  If this
     occurs, the file creation mask will be restored before setmode() returns.
     If	the calling program changes the	value of its file creation mask	after
     calling setmode(),	setmode() must be called again if getmode() is to mod-
     ify future	file modes correctly.

     If	the mode passed	to setmode() is	invalid	or if memory cannot be allo-
     cated for the return value, setmode() returns NULL.

     The value returned	from setmode() is obtained from	malloc() and should be
     returned to the system with free()	when the program is done with it, gen-
     erally after a call to getmode().

ERRORS
     The setmode() function may	fail and set errno for any of the errors spec-
     ified for the library routine malloc(3).

SEE ALSO
     chmod(1), stat(2),	umask(2), malloc(3)

HISTORY
     The getmode() and setmode() functions first appeared in 4.4BSD.
