Using DebugLogFilePath to Debug a Crash

If a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here. Unicode C

#include <C_CkCrypt2W.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkCrypt2W crypt;

    success = FALSE;

    //  If a crash is suspected to occur within a Chilkat method call, it can be debugged using the VerboseLogging and DebugLogFilePath as shown here.
    //  
    //  NOTE: The same technique applies for any Chilkat class that has the DebugLogFilePath property.
    //  Most Chilkat classes have DebugLogFilePath.

    crypt = CkCrypt2W_Create();

    //  First make sure VerboseLogging is turned on.
    CkCrypt2W_putVerboseLogging(crypt,TRUE);

    //  Set the DebugLogFilePath to the path of a log file that will be created automatically.
    //  If the file already exists, Chilkat will append to it.
    CkCrypt2W_putDebugLogFilePath(crypt,L"c:/someDir/debugLog.txt");

    //  Reproduce the problem.

    //  ...
    success = CkCrypt2W_VerifyP7M(crypt,L"c:/someDir/someFile.p7m");
    //  ...

    //  If a crash occurred within Chilkat, then the debugLog.txt will contain information that
    //  can be sent to support@chilkatsoft.com

    //  ------------------------------------------------------------------------------------------------
    //  Note: Given that the debug log file is always appended, the log file might grow 
    //  to a very large size.  You can prevent the continual growth of the log file by
    //  deleting the log file at certain points, such as after a Chilkat method returns.
    //  
    //  Given that we're only interested in the log file for Chilkat calls that crash or hang,
    //  it's OK to delete the log file after a Chilkat method that returns.
    //  
    //  The next call to a Chilkat method will re-create the log file.  If the Chilkat call crashes
    //  or hangs, then you'll be left with just the log of the crash or hang.
    //  ------------------------------------------------------------------------------------------------
