plexit: Error exit

This routine is called in case an error is encountered during execution of a PLplot routine. It prints the error message, tries to release allocated resources, calls the handler provided by plsexit and then exits. If cleanup needs to be done in the driver program then the user may want to supply his/her own exit handler and pass it in via plsexit. This function should either call plend before exiting, or simply return.

message (char *, input) Error message.
