Handle failed log buffer delete in C Media Driver

[mjpt777]

The Java Media Driver attempts the delete the log buffer during the slow tick of the conductor duty cycle and if it fails it increments the FREE_FAILS counter and tries again in the next cycle. The C Media Driver should do similar to support Windows.

This will not be picked up until the C Media Driver officially supports Windows.

Hi @mjpt777
How is that different on Windows compared to the Linux version ?
Do you have some pointers on how to start looking at this ?
Thanks

You can see the Java driver conductor attempting to free resources here. If the client still has a file open it needs to be retried later. The resources such as publications and images need to support separate free and close operations.
