Allows an application to suspend execution and wait to get awakened when data feeds arrive.

#include sys/Rsi.h
void RSiMainLoop(msecs) int msecs;
The RSiMainLoop subroutine:
To work properly, the RSiMainLoop subroutine requires that at least one RSiOpen (RSiOpen Subroutine) call has been successfully completed and that the connection has not been closed.
This subroutine is part of the Performance Toolbox for AIX licensed product.
msecsThe minimum elapsed time in milliseconds that the subroutine should continue to attempt receives before returning to the caller. Notice that your program releases control for as many milliseconds you specify but that the callback functions defined on the RSiOpen call may be called repetitively during that time.
All RSI subroutines use external variables to provide error information. To access these variables, an application program must define the following external variables:
If the subroutine returns without an error, the RSiErrno variable is set to RSiOkay and the RSiEMsg character array is empty. If an error is detected, the RSiErrno variable returns an error code, as defined in the enum RSiErrorType. RSi error codes are described in List of RSi Error Codes.
