在Windows上如何将C-String转换为LPCSTR

#include <Windows.h>

LPCSTR CStringToLPCSTR(const char* cString) {
    // 获取C-String的长度
    int length = strlen(cString);

    // 获取所需缓冲区大小
    int bufferSize = MultiByteToWideChar(CP_ACP, 0, cString, length, NULL, 0);

    // 分配缓冲区
    WCHAR* wideString = new WCHAR[bufferSize];

    // 转换C-String为宽字符（Wide Character）字符串
    MultiByteToWideChar(CP_ACP, 0, cString, length, wideString, bufferSize);

    // 获取所需缓冲区大小
    bufferSize = WideCharToMultiByte(CP_ACP, 0, wideString, bufferSize, NULL, 0, NULL, NULL);

    // 分配缓冲区
    char* lpcstr = new char[bufferSize];

    // 转换宽字符（Wide Character）字符串为LPCSTR
    WideCharToMultiByte(CP_ACP, 0, wideString, bufferSize, lpcstr, bufferSize, NULL, NULL);

    // 释放内存
    delete[] wideString;

    return lpcstr;
}

int main() {
    const char* cString = "Hello, World!";

    LPCSTR lpcstr = CStringToLPCSTR(cString);

    // 使用LPCSTR，如输出到控制台
    printf("%s\n", lpcstr);

    // 释放内存
    delete[] lpcstr;

    return 0;
}
