| 25 | .Fn Sigsetmask | |
| 26 | sets the current signal mask | |
| 27 | Signals are blocked from delivery if the | |
| c1572d77 | 28 | corresponding bit in |
| 931b8415 | 29 | .Fa mask |
| c1572d77 | 30 | is a 1; the macro |
| 931b8415 | 31 | .Fn sigmask |
| c1572d77 | 32 | is provided to construct the mask for a given |

| 40 | to be blocked. | |
| 41 | .Sh RETURN VALUES | |
| 9b494949 | 42 | The previous set of masked signals is returned. |
