Auxiliary Messages


Communicating with Simulators

Description

SESDLSIGNAL is sent by an SDL simulator when it sends an SDL signal to its SDL environment. Other simulators (or any applications connected to the PostMaster) can then receive the message and send back messages of the same type.

The PIds consist of a UNIX PId (on UNIX), or an identifier "pid" known by the PostMaster (in Windows), in both cases an integer, and an SDL process instance number (a hex number), which normally is used only in comparisons. The PIds may be used to uniquely identify a single receiver if several receivers exist, but can be ignored if only two tools are communicating
