@(#)setmode.3 5.1 (Berkeley) 02/01/90

C 7 getmode, setmode - modify mode bits

getmode(mode)
mode_t mode;

setmode(mode_str)
char *mode_str;

Getmode returns the file permission bits mode as altered by the string specified to setmode . 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. 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 modify future file modes correctly.

If the mode passed to setmode is valid, setmode returns 0; otherwise it returns -1.

Neither getmode or setmode set the external variable errno . chmod(1), stat(2), umask(2)
