Application-Defined Functions

MyProcessCallbackFunction

Open Transport calls your process callback function when the scheduled task associated with it occurs. You use this function to specify Open Transport functions that you want to execute at specific system or deferred task times.

C INTERFACE

void MyProcessCallbackFunction(void* arg)

C++ INTERFACES

None. C++ applications use the C interface to this function.

PARAMETERS

arg

A pointer to application-defined data, typically providing context information.

DESCRIPTION

The OTCreateSystemTask and the OTCreateDeferredTask functions return a reference that identifies the newly created task so that you can schedule it for execution at specified times. Among other data, the task contains a pointer to your process callback function. When the scheduled task-execution time occurs, Open Transport calls your process callback function and passes it the data in the arg parameter.
