NAME

csignal − specify Fortran action upon receipt of a system signal

SYNOPSIS

integer cursig
integer signum
external proc
integer flag

cursig = csignal (signum, proc, flag)

DESCRIPTION

csignal allows a process to specify a function to be invoked or an action to be taken upon receipt of a specific signal.  signum specifies the desired signal.  proc is the name of the function to be invoked upon receipt of the signal.  flag is:      negative, if the specified function is to be invoked;
     0,        if the system default action is to be taken;
     1,        if the signal is to be ignored by the system. cursig is the value returned by signal(2). 

SEE ALSO

kill(2), signal(2), signal(3F). 

NOTES

When compiling source with the -Qocs option, this routine is not accessible because it it takes a procedure argument, which is passed differently under the 88Open OCS standard.
