Hi Rok Dolenc,

1) About gOutputFile = fopen(outputPath, “w”);
From http://www.cplusplus.com/reference/cstdio/fopen/
you can read: “w” write: Create an empty file for output operations. If a file with the same name already exists, its contents are discarded and the file is treated as a new empty file.

-> I don’t even understand why it doesn’t overwrite, but append. Strange and not logical ..

2) Here: https:/sdk/XPLMRegisterFlightLoopCallback/
you can read: inInterval defines when you will be called:
– Positive number to specify seconds from registration time to the next callback
– Negative number to indicate when you will be called (e.g. pass -1 to be called at the next cylcle)
– 0 to not be called; your callback will be inactive.

-> But for me the file (TimedProcessing.txt) is written about every 60/70 seconds instead of every second.

Have you found a solution?
