# WAKNO

**xcall WAKNO, jobno \{,status\}**

WAKNO (Unix only) wakes up a job that is sleeping (in SLEEP or SLEEP.LIT).

**Parameters**

_jobno_  \[in\]

is the job number of the job to wake up. (See [PLYJOB](plyjob.md) for a way of getting the number of another job.) Note that in order to be able to send a signal like this to another process under Unix, you either have to be the superuser or have the same effective user id as the target user.  

_status_  \[out\]  optional

returns the result of the operation:

| **Value** | **Description** |
|------|------|
| \-1 | No such job |
| 0 | Success |
| 1 | Insufficient privileges to wake target user |
| 3 | No such process (job probably aborted uncleanly, leaving a phantom in the job table) |
