CONTROL Procedure
•
Interprocess communication
•
Nonstandard operation and parameter values
Any value can be specified for the
operation and parameter parameters.
An application-defined protocol should be established for interpreting
nonstandard parameter values.
•
Process not accepting system messages
If the object of the control operation is not accepting process CONTROL
messages, the call to CONTROL completes with a condition code of CCG; a
subsequent call to FILE_GETINFO_ or FILEINFO shows that an error 7
occurred.
•
Process control
You can obtain the process identifier of the caller to CONTROL in a
subsequent call to FILE_GETRECEIVEINFO_ (or LASTRECEIVE or
RECEIVEINFO).
