File in Use (FIU)
Memory Profiling for C and C++
An FIU message indicates a file that was opened, but never closed. An FIU message can indicate that the program has a resource leak.
Memory Profiling generates a list of files in use when you activate the FIU Files In Use option in the Memory Profiling Settings.
