[    uuid(7a98c250-6808-11cf-b73b-00aa00b677a7),    version(1.0)]interface hello{    void HelloProc([in, string] unsigned char * pszString);    void Shutdown(void);}

 

[    implicit_handle (handle_t hello_IfHandle)] interface hello{}

copy好后hello.idl和hello.acf运行midl hello.idl生成hello.h、hello_c.c、hello_s.c，编写helloc.c

#include <stdlib.h>#include <stdio.h>#include <ctype.h>#include "hello.h" #include "rpc.h"#include <windows.h>void main(){RPC_STATUS status;unsigned char * pszUuid             = NULL;unsigned char * pszProtocolSequence = "ncacn_ip_tcp";unsigned char * pszNetworkAddress   = "127.0.0.1";unsigned char * pszEndpoint         = "12345";unsigned char * pszOptions          = NULL;unsigned char * pszStringBinding    = NULL;unsigned char * pszString           = "hello, world";unsigned long ulCode;status = RpcStringBindingCompose(pszUuid,pszProtocolSequence,pszNetworkAddress,pszEndpoint,pszOptions,&pszStringBinding);if (status) exit(status);status = RpcBindingFromStringBinding(pszStringBinding, &hello_IfHandle);if (status) exit(status);RpcTryExcept  {HelloProc(pszString);//Shutdown();}RpcExcept(1) {ulCode = RpcExceptionCode();printf("Runtime reported exception 0x%lx = %ld\n", ulCode, ulCode);}RpcEndExceptstatus = RpcStringFree(&pszStringBinding); if (status) exit(status);status = RpcBindingFree(&hello_IfHandle);if (status) exit(status);exit(0);}/******************************************************//*         MIDL allocate and free                     *//******************************************************/void __RPC_FAR * __RPC_USER midl_user_allocate(size_t len){return(malloc(len));}void __RPC_USER midl_user_free(void __RPC_FAR * ptr){free(ptr);}

在同一个solution中new一个project，添加hellos.c

#include <stdlib.h>#include <stdio.h>#include <ctype.h>#include "hello.h"#include "rpc.h"#include <windows.h>void main(){RPC_STATUS status;unsigned char * pszProtocolSequence = "ncacn_ip_tcp";unsigned char * pszSecurity         =  NULL; unsigned char * pszEndpoint         = "12345";unsigned int    cMinCalls = 1;unsigned int    fDontWait = FALSE;status = RpcServerUseProtseqEp(pszProtocolSequence,2,pszEndpoint,pszSecurity); if (status) exit(status);status = RpcServerRegisterIf(hello_v1_0_s_ifspec,  NULL,   NULL); if (status) exit(status);status = RpcServerListen(cMinCalls,RPC_C_LISTEN_MAX_CALLS_DEFAULT,fDontWait);if (status) exit(status);}/******************************************************//*         MIDL allocate and free                     *//******************************************************/void __RPC_FAR * __RPC_USER midl_user_allocate(size_t len){return(malloc(len));}void __RPC_USER midl_user_free(void __RPC_FAR * ptr){free(ptr);}

另建一hellop.c

#include <stdio.h>#include <windows.h>void Shutdown(void){RPC_STATUS status;status = RpcMgmtStopServerListening(NULL);if (status) {exit(status);}status = RpcServerUnregisterIf(NULL, NULL, FALSE);if (status) {exit(status);}} void HelloProc(char * pszString){printf("%s\n", pszString);}

在vs2008的client和server工程里分别修改properties->linker->input->addtional dependencies，输入RpcRT4.lib

在rpc运行的过程中，可能会受到windows的安全限制，修改注册表HKEY_LOCAL_MACHINE \ SOFTWARE\Policies\ Microsoft\Windows NT\RPC ，设置Restrict
RemoteClients值为0，没有响应的项就添加

若将client/server中的一端拿到没有支持vs2008的c/c++运行库的vm中，设置properties->c/c++->code generation->runtime library为multi-threaded debug
