sendsig(3)
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.
