About the VCS Error Reporting System

The VCS error reporting system provides information to assist you in finding where an error occurred and what the error is. It is only available when using the development libraries. If the error involves memory corruption, assistance is provided in detecting and locating overwrites of memory.

The information provided by the VCS error reporting system is as follows:

• nA call log, which lists all the functions called in the main program up to and including the time of the error.
  
  
• nA call stack, which lists the functions that were open or active when the error was reported.
  
  
• nThe error message associated with the error code that triggered the error reporting system. If no error message is associated with the error code, just the number of the error code is reported.
  
  
• nIf the error involves memory corruption, a dump (in hex and ASCII) of the affected region of memory is displayed.

Only those functions that contain the conditional code to call the error reporting function are included in the call log and call stack lists. All Vermont Views functions that set VV_ERR include this conditional code. You can add the code to your own modules to ensure that they too appear in the call log and call stack lists.
