RAISEQQ

Run-Time Function: Sends a signal to the executing program.

Module: USE DFLIB

Syntax

result = RAISEQQ (sig)

sig
(Input) INTEGER(4). Signal to raise. One of the following constants (defined in DFLIB.F90 in the \DF98\INCLUDE subdirectory):

• SIG$ABORT - Abnormal termination
• SIG$FPE - Floating-point error
• SIG$ILL - Illegal instruction
• SIG$INT - CTRL+C signal
• SIG$SEGV - Illegal storage access
• SIG$TERM - Termination request

If you do not install a signal handler (with SIGNALQQ, for example), when a signal occurs the system by default terminates the program with exit code 3.

Results:

The result is of type INTEGER(4). The result is zero if successful; otherwise, nonzero.

If a signal-handling routine for sig has been installed by a prior call to SIGNALQQ, RAISEQQ causes that routine to be executed. If no handler routine has been installed, the system terminates the program (the default action).
