MesInqProcEncodingId

The MesInqProcEncodingId function provides the identity of an encoding.

#include <rpc.h>
#include <midles.h>
RPC_STATUS RPC_ENTRY MesInqProcEncodingId( 
  handle_t  Handle,                       
  PRPC_SYNTAX_IDENTIFIER  pInterfaceId,   
  unsigned long  *  pProcNum              
);

Parameters

Handle: Specifies an encoding or decoding handle.
pInterfaceId: Points to the address in which the identity of the interface used to encode the data will be written. pInterfaceId consists of the interface UUID and the version number.
pProcNum: Specifies the number of the routine used to encode the data.

Remarks

The MesInqProcEncodingId routine is used by applications to obtain the identity of the routine used to encode the data before calling a routine to decode it. When called with an encoding handle, it returns the identity of the last encoding operation. When called with a decoding handle, it returns the identity of the next decoding operation by pre-reading the buffer.

This routine can only be used to check the identity of a procedure encoding; it cannot be used to check the identity for a type encoding.
