Calculate pointer position for N lines above the current position.
Calculate pointer position for N lines above the current displaying position within the given buffer. Used by KdbpPager().

Debug logger function.
This function writes text strings into KdpDmesgBuffer, using it as a circular buffer. KdpDmesgBuffer contents can be later (re)viewed using the dmesg command. KdbDebugPrint() protects KdpDmesgBuffer from simultaneous writes by use of KdpDmesgLogSpinLock.

Called when KDB is initialized.
Loads the KDBinit file from the \SystemRoot\System32\drivers\etc directory and interprets it, by calling back into the debugger.

Interprets the KDBinit file from the \SystemRoot\System32\drivers\etc directory, that has been loaded by KdbpCliInit().
This function is used to interpret the init file in the debugger context with a trap frame set up. KdbpCliInit() enters the debugger by calling DbgBreakPointWithStatus(DBG_STATUS_CONTROL_C). In turn, this will call KdbEnterDebuggerException() which will finally call this function if KdbInitFileBuffer is not NULL.
