Using Library Routines to Control Tracing

The library routines provide a means of obtaining the same tracing behavior as setting the FCD flags without the need to have the FCD available. All changes to tracing behavior made using the library routines affect all files subsequently accessed.

To control tracing, issue calls to the MFFH_MODIFY_TRACE library routine. You can:

• Set the main tracing flag on and off
• Set the OPEN/CLOSE tracing flag on and off
• Disable a modification that you set earlier

To disable all the modifications that you have set, issue a call to the library routine MFFH_MODIFY_DISABLE.

For further information see the topics MFFH_MODIFY_TRACE and MFFH_MODIFY_DISABLE.
