[ACCEPTED]-Reading default FileMode when using os.O_CREATE-umask

Accepted answer

Score: 10

It already works like you want it.

Just use 4 "0666" and the umask will be applied.

f, err := os.OpenFile(fpath, os.O_CREATE|os.O_WRONLY, 0666)

For 3 me with umask 0022 I get:

$ go run x.go  ; ls -l filename
-rw-r--r--  1 ask  wheel  0 May 24 00:18 filename

Use 0660 (for example) if 2 you always want the file to be unreadable 1 by "other", no matter the umask.
