You can use functions that are exposed by the WDbgExts_CE.h header file in debugger extension commands. When developing a debugger extension, these functions can be helpful in controlling and examining the target device being debugged.
The following table shows debugger extension functions.
| Programming element | Description |
|---|---|
| CheckControlC | This function checks to see whether the user pressed the CTRL+C key combination. |
| Disassm | This function disassembles an instruction and stores in a buffer a string that can be printed. |
| dprintf | This function prints a formatted string to the command window for the debugger. |
| EXTSTACKTRACE | This structure specifies stack frames for the StackTrace function. |
| GetContext | This function obtains the context of the process being debugged. |
| GetDebuggerData | This function retrieves information stored in a data block. |
| GetExpression | This function returns the value of an expression. |
| GetSetSympath | This function obtains or sets the search path for symbols. |
| GetSymbol | This function locates the symbol nearest to a specified address. |
| Ioctl | This function is an entry point for much of the functionality provided by the extension functions for the kernel debugger. |
| ReadControlSpace | This function reads a CPU-specific control space into an array. |
| ReadMemory | This function reads memory from the process being debugged.
The entire area of memory must be accessible, or the operation fails. |
| ReadPhysical | This function reads from physical memory. |
| SetContext | This function sets the context of the process being debugged. |
| SetThreadForOperation | This function specifies a thread to use for the next call to the StackTrace function |
| StackTrace | This function receives a stack trace for the process being debugged. |
| WriteIoSpace | This function writes to system I/O locations. |
| WriteMemory | This function writes memory to a process being debugged.
The entire area of memory must be accessible, or the operation fails. |
| WritePhysical | This function writes to physical memory. |
