即使我之前調用了CreateNamedPipe,我仍然掛在WaitNamedPipe函數上。由於waitnamedpipe函數只是等待管道的啓動,爲什麼?代碼如下。感謝命名管道,服務器問題

PROCESS_INFORMATION po; 
STARTUPINFO 
s; 

GetStartupInfo (&s); 

if(CreateProcess ("c:\s2.exe", NULL, NULL, NULL, false, 0, NULL, 
        NULL, &s, &po) == FALSE) 
{ 
    printf("Error %d starting CC\n", 
      GetLastError()); 
    exit(-1); 

} 

HANDLE pipe=CreateNamedPipe (pipe_name, 0x00000003, 
          FILE_FLAG_FIRST_PIPE_INSTANCE, 
          PIPE_UNLIMITED_INSTANCES,128, 128, 0, 
          NULL); 

while(WaitNamedPipe(pipe_name, INFINITE)==FALSE) Sleep(300); 

HANDLE CC = CreateFile (pipe_name, GENERIC_READ | GENERIC_WRITE, 0, NULL, 
         OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 
         NULL); 

bool fConnected = ConnectNamedPipe(pipe, NULL) ? TRUE : 
        (GetLastError() == 
        ERROR_PIPE_CONNECTED); 

if(fConnected) printf("true"); 
else printf("false"); 
+4

有一個實際的問題嗎?我確定沒有看到一個。 – 2011-01-28 08:10:21
