TNS/R native signal
TNS/R native signal. A signal model available to TNS/R native processes in the Guardian
and OSS environments. TNS/R native signals are used for error exception handling.
trap. A software mechanism that stops program execution and holds the cause of a
processing problem. In TNS Guardian processes, traps occur as the result of errors
that prevent the continued execution of the code stream. Contrast with signal.
trap handler. A location in a program where execution begins if a trap occurs. A process
can specify a trap handler by a call to the ARMTRAP procedure.
unconverted process. A process that does not take advantage of the extended features of
D-series systems. Contrast with converted process.
unnamed process. A process to which a process name was not assigned when the
process was created. Contrast with named process.
user process. A process whose primary purpose is to solve a user’s problem. A user
process is not essential to the availability of a processor module. A user process is
created only when the user explicitly creates it. Contrast with system process.
