.SH NAME
getmode, setmode \- modify mode bits
.SH SYNOPSIS
.nf
.ft B
getmode(mode)
mode_t mode;

setmode(mode_str)
char *mode_str;
.ft R
.fi
.SH DESCRIPTION
.I Getmode
returns the file permission bits
.I mode
as altered by the string specified to
.IR setmode .
While only the mode bits are altered, other parts of the file mode
may be examined.
.PP
.I Setmode
takes an absolute (octal) or symbolic value, as described in
.IR chmod (1),
as an argument.
Because some of the symbolic values are relative to the file
creation mask,
.I setmode
may call
.IR umask (2).
If this occurs, the file creation mask will be restored before
.I setmode
returns.
If the calling program changes the value of its file creation mask
after calling
.IR setmode ,
.I setmode
must be called again if
.I getmode
is to modify future file modes correctly.
.PP
If the mode passed to
.I setmode
is valid,
.I setmode
returns 0; otherwise it returns -1.
.SH ERRORS
Neither
.I getmode
or
.I setmode
set the external variable
.IR errno .
