- /* These Macros are useful when trying to tune performance to see approximately how long in milliseconds certain lines of
- * code are taking. The output will display approximately how long it took for the lines between checkpoints.
- *
- * Available macros in this file and how to use them:
- *
- * HX_ENABLE_CHECKPOINTS_FOR_MODULE(pModuleName, pOutputFileName)
- * This macro should be used once for the entire dll or exe you are compiling. It declares a global that is used by the
- * entire module. A good place to put this for example would be in the dllmain.cpp file.
- *
- * pModuleName - The name of the directory in which the dll or exe you are compiling is located. This is used
- * in the log when printing out the file name.
- * pOutputFileName - The name of the output file name where checkpoint data is dumped
- *
- * HX_LOG_INITIAL_CHECKPOINT(pFunctionName)
- * This macro should be used once at the beginning of each function or method you are interested in timing.
- *
- * pFunctionName - The name of the function that the checkpoints are in
- *
- * HX_LOG_CHECKPOINT(pComment)
- * This macro should be used whenver timing blocks of code are of interest. This can be used repeatedly in each function.
- *
- * pComment - The comment passed in will be dumped to the log file. It is used as a hint to what was being executed
- * for this checkpoint instead of having to refer back to the code.
- *
- * HX_LOG_BLOCK( pComment )
- * This macro logs entry to and exit from a brace delimited block. It writes out two checkpoints - the entry checkpoint
- * will be the comment prefixed with 'Enter', the exit checkpoint will be the comment prefixed with 'Exit'
- * Note that this macro cannot be used in the same block as HX_LOG_INITIAL_CHECKPOINT.
- *
- * pComment - An identifier for the block. Since blocks often correspond to functions this will often be the function name.
- *
- *
- * LOG FILE FORMAT
- * The log file is written to in append mode and is several fields delimited by a ;
- * It can easily be loaded into a spreadsheet app since all of them should be able to read delimted text files.
- * Here is a breakdown of the individual fields:
- * Field1: Time elapsed since the last checkpoint
- * Field2: Time elapsed since the first checkpoint in the function
- * Field3: Time elapsed since the first checkpoint in the module
- * Field4: Tick count as reported from the OS
- * Field5: Path to file name
- * Field6: Function name
- * Field7: Line Number of checkpoint
- * Field8: Comment about what the checkpoint is timing
