SETMODE(3)SETMODE(3)NAME
getmode, setmode - modify mode bits
SYNOPSIS
getmode(set, mode)
mode_t *set, mode;
set = setmode(mode_str)
mode_t *set;
char *mode_str;
DESCRIPTION
Getmode 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.
Setmode takes an absolute (octal) or symbolic value, as described in
chmod(1), as an argument and returns a pointer to mode values 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 call‐
ing setmode, setmode must be called again if getmode is to modify
future file modes correctly.
If the mode passed to setmode is invalid, setmode returns NULL.
ERRORS
Setmode may fail and set errno for any of the errors specified for the
library routine malloc(3).
