RPC Runtime Library Functions (RpcRt4.h)

This section details the functions available in the RPC Runtime Library, primarily defined in the RpcRt4.h header file. These functions facilitate the creation and management of Remote Procedure Call (RPC) clients and servers.

Function Categories

The RPC Runtime Library functions can be broadly categorized into the following areas:

Binding Functions
Communication Management Functions
Error Handling Functions
RPC Management Functions
Security Functions
String Handling Functions
Transport Management Functions

Binding Functions

These functions are used to establish and manage bindings between RPC clients and servers.

RpcBindingBind
RpcBindingCreateAndBind
RpcBindingFree
RpcBindingInqOption
RpcBindingSetOption
RpcBindingVectorFree

Communication Management Functions

Manage the flow of data and communication state between clients and servers.

RpcSend
RpcReceive
RpcGetBuffer
RpcGetBufferWithHeap
RpcReleaseBuffer
RpcCompleteBuffer

Error Handling Functions

Retrieve and manage RPC-specific error information.

RpcErrorInqErrorText
RpcErrorGet
RpcErrorStringBindingInqErrorText

RPC Management Functions

Functions for initializing, managing, and terminating the RPC environment.

RpcInitialize
RpcMgmtHandle
RpcMgmtIsServerListening
RpcServerListen
RpcServerStopListening
RpcStringFree

Security Functions

Handle security aspects of RPC communication.

RpcImpersonateClient
RpcRevertToSelf
RpcBindingSetAuthInfo
RpcBindingInqAuthInfo

String Handling Functions

Manipulate and convert RPC-specific string formats.

RpcStringBindingAssign
RpcStringBindingParse
RpcStringHandleFree
RpcStringException

Transport Management Functions

Functions to manage underlying transport protocols.

RpcTransportCreate
RpcTransportClose
RpcTransportGetOption
RpcTransportSetOption

Example Function Detail

`RpcBindingCreateAndBind`

Creates a binding handle and binds to an RPC server.

RPC_STATUS RpcBindingCreateAndBind(
    [in] RPC_CLIENT_INTERFACE *pInterface,
    [in] RPC_BINDING_HANDLE *pBindingHandle,
    [in] UUID *pUuid,
    [in] RPC_WSTR pszStringBinding,
    [in] RPC_WSTR pszOptions
);

Parameters

pInterface: Pointer to the client interface structure.
pBindingHandle: Pointer to a binding handle to be created.
pUuid: Pointer to the UUID of the server interface.
pszStringBinding: String binding that specifies the network address and protocol sequence.
pszOptions: String specifying RPC binding options.

Return Value

Returns RPC_S_OK on success, or an RPC error code otherwise.

Note: This function is typically used in client applications to establish a connection to an RPC server. The pszStringBinding parameter specifies how to locate the server.
