【求助】WINAPI GetComputerName报错

蒟蒻

如题，目前已经确认了动态内存分配没有问题，SetText没有问题（上面还有一个格式一摸一样的MyGetUserName）

GetComputerName时，会返回FALSE

[C] 纯文本查看 复制代码

char *MyGetComputerName() {
    char *computerName = (char *)malloc(256 *sizeof(char));
    DWORD strSize = sizeof(computerName);
    if (computerName == NULL) {
        // 内存分配失败
        SetText(RED);
        printf(
            "[Fatal] in %s, line %d, the function %s, the variable %s's memory not allocated correctly\n",
            __FILE__,__LINE__,"MyGetComputerName(char*)","computerName(char*)"
        );
        SetText(WHITE);
        return NULL;
    }

    if (GetComputerName(computerName, &strSize)) {
        return computerName;
    } else {
        SetText(RED);
        printf(
            "[Fatal] in %s, line %d, the function %s, the variable %s's value not assignment correctly\n",
            __FILE__,__LINE__,"MyGetComputerName(char*)","computerName(char*)"
        );
        SetText(WHITE);
        return NULL;
    }
}
