Report Memory Errors

You can report memory leaks and memory overwrites in the log file by enabling the memory trace system, either by using the API or environment variables. If the memory trace system is enabled, the extended error codes for memory leaks and memory overwrites (26 and 27, respectively) are reported in the log file when they are generated. The extended error codes are defined in KVErrorCodeEx in kvtypes.h.

NOTE:

To report memory overwrites, you must also set a memory guard. See Specify a Memory Guard.

Use the API

To enable or disable the memory trace system, set the final argument (dwFlags) of fpInit() or fpOpenStreamEx2() to either KVF_OOPMEMTRACEON or KVF_OOPMEMTRACEOFF.

Use Environment Variables

To enable the memory trace system, add the KVOOPMT environment variable, and set its value to 1. To disable the memory trace system, do not set the KVOOPMT environment variable.
