chmod -- Changes file mode


int chmod ( string filename, int mode)

Attempts to change the mode of the file specified by filename to that given in mode.

Note that mode is not automatically assumed to be an octal value, so strings (such as "g+w") will not work properly. To ensure the expected operation, you need to prefix mode with a zero (0):

chmod ("/somedir/somefile", 755);   // decimal; probably incorrect   
chmod ("/somedir/somefile", "u+rwx,go+rx"); // string; incorrect       
chmod ("/somedir/somefile", 0755);  // octal; correct value of mode

Siker esetén TRUE értékkel tér vissza, ellenkező esetben FALSE értéket ad.
