The umask is used by open(2) to set initial file |
| |
|
30 |
permissions on a newly-created file. Specifically, |
| |
|
31 |
permissions in the umask are turned off from the __mode__ |
| |
|
32 |
argument to open(2) (so, for example, the common |
| |
|
33 |
umask default value of 022 results in new files being |
| |
|
34 |
created with permissions 0666 |
| |
|
35 |
__mode__ is specified as |
| |
|
36 |
0666). |

This system call always succeeds and the previous value of |

the mask is returned. |
