不是cd 不是cd 不是cd

安装教程

第一步：获取二进制

1.从源码构建
你需要MVSC才能从源码构建！
将代码写入pwd.c：

#pragma comment(linker, "/subsystem:console")
#pragma comment(linker, "/entry:mainCRTStartup")
#pragma comment(lib, "kernel32.lib")

unsigned long __stdcall GetCurrentDirectoryW(
    unsigned long nBufferLength,
    unsigned short* lpBuffer
);

void* __stdcall GetStdHandle(
    unsigned long nStdHandle
);

int __stdcall WriteFile(
    void* hFile,
    const void* lpBuffer,
    unsigned long nNumberOfBytesToWrite,
    unsigned long* lpNumberOfBytesWritten,
    void* lpOverlapped
);

void __stdcall ExitProcess(
    unsigned int uExitCode
);

#define STD_OUTPUT_HANDLE ((unsigned long)-11)

void mainCRTStartup(void) {
    unsigned short path[32768];
    unsigned long written;

    unsigned long len =
        GetCurrentDirectoryW(32768, path);

    void* h =
        GetStdHandle(STD_OUTPUT_HANDLE);

    WriteFile(
        h,
        path,
        len * 2,
        &written,
        0
    );

    ExitProcess(0);
}
