+//! is to continue calling the other unhandled exception filters in the unhandled exception chain.
+#define MDSF_FORCEEXIT          0x0002
+
+//! This flag prevents other threads in the process from hijacking the Exception filter.
+//! It is useful when you want to prevent 3rd party libraries included with your application
+//! or the Operating System from disabling BugSplat integration.
+//! It is *recommended* that you use this setting
+#define MDSF_PREVENTHIJACKING   0x0004
+
+//! This flag launches the BugSplatHD.exe process with the current process id.
+//! The process runs in low priority, and periodically performs tests on the main process id 
+//! to determine if it has hung.
+//! The burden on the OS is extremely low, and will only consume a few CPU cycles 
+//! each minute.
+#define MDSF_DETECTHANGS        0x0008
+
+//! The guard memory flag causes the BugSplat library to pre-allocate a 4MB (default) chunk of data
+//! on the heap. When a crash is encountered, this heap data is deleted and might be useful
+//! in low memory scenarios.  The size of the buffer can be controlled using setGuardByteBufferSize();
+#define MDSF_USEGUARDMEMORY     0x0010
+
+//! BugSplat operates using the SetUnhandledExceptionFilter method. Use this flag if you want to
+//! use your own exception handling mechanism instead.
+//! To initiate a BugSplat crash report, you need to call unhandledExceptionHandler within your own
+//! exception filter method
+#define MDSF_CUSTOMEXCEPTIONFILTER 0x0020
+
+//! EXPERIMENTAL
+//! Use this flag to suspend all threads in the process prior to capturing the
+//! crash report data. This might be used to prevent security libraries from detecting
+//! the debugging commands used by BugSplat and terminating the app before the 
+//! crash has a chance to be reported.
+#define MDSF_SUSPENDALLTHREADS  0x0800
+
+//! These flags control output of the BugSplat log output, typically used for development/debugging.
