MesInqProcEncodingId function (midles.h)

  • Article

The MesInqProcEncodingId function provides the identity of an encoding.

Syntax

RPC_STATUS MesInqProcEncodingId(
  handle_t               Handle,
  PRPC_SYNTAX_IDENTIFIER pInterfaceId,
  unsigned long          *pProcNum
);

Parameters

Handle

An encoding or decoding handle.

pInterfaceId

Pointer to the address in which the identity of the interface used to encode the data will be written. The pInterfaceId consists of the interface universally unique identifier UUID and the version number.

pProcNum

Number of the function used to encode the data.

Return value

Value Meaning
RPC_S_OK
 The call succeeded.
RPC_S_INVALID_ARG
 The argument was not valid.
RPC_S_OUT_OF_MEMORY
 Out of memory.
RPC_S_UNKNOWN_IF
 Unknown interface.
RPC_S_UNSUPPORTED_TRANS_SYN
 Transfer syntax not supported by server.
RPC_X_INVALID_ES_ACTION
 Operation for a given handle was not valid.
RPC_X_WRONG_ES_VERSION
 Incompatible version of the serializing package.
RPC_X_SS_INVALID_BUFFER
 Buffer not valid.
 
Note  For a list of valid error codes, see RPC Return Values.
 

Remarks

The MesInqProcEncodingId function is used by applications to obtain the identity of the function used to encode the data before calling a function 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 function can only be used to check the identity of a procedure encoding; it cannot be used to check the identity for a type encoding.
