!rpcexts.getclientcallinfo

  • Article

The !rpcexts.getclientcallinfo extension searches the system's RPC state information for client call (CCALL) information.

!rpcexts.getclientcallinfo [ CallID | 0 [ IfStart | 0 [ ProcNum | 0xFFFF [ProcessID|0] ] ] ] 
!rpcexts.getclientcallinfo -?

Parameters

CallID
Specifies the call ID. This parameter is optional; include it if you only want to display calls matching a specific CallID value.

IfStart
Specifies the first DWORD of the interface UUID on which the call was made. This parameter is optional; include it if you only want to display calls matching a specific IfStart value.

ProcNum
Specifies the procedure number of this call. (The RPC Run-Time identifies individual routines from an interface by numbering them by position in the IDL file -- the first routine in the interface is 0, the second 1, and so on.) This parameter is optional; include it if you only want to display calls matching a specific ProcNum value.

ProcessID
Specifies the process ID (PID) of the client process that owns the calls you want to display. This parameter is optional; omit it if you want to display calls owned by multiple processes.

-?
Displays some brief Help text for this extension in the Command Prompt window.
