TMS320F2808的完整驱动测试程序源码

*         0 - False/Failure. The function did not complete without error.
*         The error will be queued into the event queue.
*
* POINTERS : 
*         Again following the Microsoft convention all pointer arguments
*         are checked for NULL.  If a pointer is NULL then input arguments
*         are not used and return arguments are not returned.  Example,
*         if you call GetLastError and set pErrString to NULL then no
*         error string is returned.

// Interface config functions
//
// CreateHndl : Create a handle for this debug instance.  If pLibPath and 
//              pLibName are not NULL then use the specified debug library.
//              Else, pDevName must hold the name of the processor family
//              to connect to.  If all three parameters are provided then
//              pFamily will be used to validate the loaded lib..
//              A valid handle is returned except in the rare case of
//              insufficent host memory.  Thus you can call GetLastError
//              if there is an error during CreateHndl.
//
// FreeHndl :   Free the handle from CreateHndl.  Closes the open 
//              debug session if required.  You MUST always call
//              this to release resources if CreateHndl returns
//              a valid handle. FreeHndl will automaticly "Disconnect"
//              if the debug session is still "Connected".
//
// SetOptions : Set the options for this debug session. Options are
//              generally setup prior to connecting to a target. 
//              Options are in the form of "EmulatorId=378,...",
//              using a comma seperator and null terminator.  Once 
//              connected some options cannot be changed until you
//              disconnect, for example your EmulatorId.
//
// GetOptions : Return the current options.  MaxString is the maximum
//              size of the return string.             
//
// FreeOptions : Free the current options and return to the default
//               state. FreeOptions can only be called when in the
//               disconnected state.  You can change current options
//               by calling SetOptions with the restriction that not
//               all options can be changed while in the connected 
//               state.
//
// Connect :     Make a debug connection to the target.  Once connected the
//               target is ready for a debug session.
//
// Disconnect : Disconnect from the debug session. Once disconnected no
//              more target accesses are allowed.
//
// GetErrorString : Get an error string based on the error number
//
