使用此处找到的客户端和服务器示例:http: //www.winsocketdotnetworkprogramming.com/winsock2programming/winsock2advancedmailslot14.html使用 VS2008 编译它们,运行服务器,然后运行“客户端 Myslot”,我不断收到“WriteFail failed with error 53”。有人有想法么?也欢迎提供其他 Mailslot 示例的链接,谢谢。

服务器:

    // Server sample
#include <windows.h>
#include <stdio.h>

void main(void)
{

    HANDLE Mailslot;
    char buffer[256];
    DWORD NumberOfBytesRead;

    // Create the mailslot

    if ((Mailslot = CreateMailslot("\\\\.\\Mailslot\\Myslot", 0, MAILSLOT_WAIT_FOREVER, NULL)) == INVALID_HANDLE_VALUE)
    {
        printf("Failed to create a mailslot %d\n", GetLastError());
        return;
    } 

    // Read data from the mailslot forever!

    while(ReadFile(Mailslot, buffer, 256, &NumberOfBytesRead, NULL) != 0)
    {
        printf("%.*s\n", NumberOfBytesRead, buffer);
    }
}

客户:

// Client sample

#include <windows.h>
#include <stdio.h>

void main(int argc, char *argv[])
{
    HANDLE Mailslot;
    DWORD BytesWritten;
    CHAR ServerName[256];

    // Accept a command line argument for the server to send a message to

    if (argc < 2)
    {
        printf("Usage: client <server name>\n");
        return;
    }

    sprintf(ServerName, "\\\\%s\\Mailslot\\Myslot", argv[1]);

    if ((Mailslot = CreateFile(ServerName, GENERIC_WRITE,

        FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL)) == INVALID_HANDLE_VALUE)
    {
        printf("CreateFile failed with error %d\n", GetLastError());
        return;
    }

    if (WriteFile(Mailslot, "This is a test", 14, &BytesWritten, NULL) == 0)
    {
        printf("WriteFile failed with error %d\n", GetLastError());
        return;
    }

    printf("Wrote %d bytes\n", BytesWritten);
    CloseHandle(Mailslot);
}

错误 53 是 ERROR_BAD_NETPATH,“找不到网络路径”。显然,您为邮槽使用了错误的服务器名称。\\.\mailslot\blah如果服务器与您的客户端在同一台机器上运行,请使用此选项。并且不要忘记在字符串中转义反斜杠:"\\\\.\\mailslot\\blah"

我将发布的代码完全复制到两个文件中,用 VS2008 编译它们,它们运行完美。如果您的客户端程序编译为 client.exe,则键入以下命令:

client .

或者

client <computername>

其中计算机名称是不带域的 PC 名称。您可以调用 API GetComputerName来检索名称。
