# pvm\_sendsig(3)

Sends a signal to another PVM process.

## NAME

pvm\_sendsig - Sends a signal to another PVM process.

## SYNOPSIS

```
C	int info = pvm_sendsig( int tid, int signum )
Fortran	call pvmfsendsig( tid, signum, info )
```

## PARAMETERS

- tid

  **Integer task identifier of PVM process to receive the signal.**\

- signum

  **Integer signal number.**\

- info

  **Integer status code returned by the routine.**

## DESCRIPTION

**The routine** *pvm\_sendsig* **sends the signal number** *signum* **to the PVM process identified by** *tid.* **If pvm\_sendsig is successful,** *info* **will be 0.** **If some error occurs then** *info* **will be \< 0.**

**pvm\_sendsig should only be used by programmers with Unix signal handling** **experience.** **Many library functions (and in fact the PVM library functions) cannot** **be called in a signal handler context because they do not mask signals** **or lock internal data structures.**

**Further caveat:  the signal numbers passed between systems are not** **mapped - PVM assumes that signal 9 on one system is the same as on another.**

## EXAMPLES

```
C:
	tid = pvm_parent();
	info = pvm_sendsig( tid, SIGKILL);

Fortran:
	CALL PVMFBUFINFO( BUFID, BYTES, TYPE, TID, INFO );
	CALL PVMFSENDSIG( TID, SIGNUM, INFO )
```

## ERRORS

**These error conditions can be returned by** *pvm\_sendsig*

- PvmSysErr

  **pvmd not responding.**

- PvmBadParam

  **giving an invalid tid value.**
