我不得不承认，这段代码中我不熟悉的大部分 win32 api 东西。话虽如此，我想将我所知道的融入我的学习过程中。我正在尝试创建一个 for 循环，该循环将CreateProcess多次使用不同的参数。在 Visual Studio 中，我得到一个编译错误：
source.cpp(138): error C3867: 'std::basic_string<_Elem,_Traits,_Alloc>::c_str': function call missing argument list; use '&std::basic_string<_Elem,_Traits,_Alloc>::c_str' to create a pointer to member
1> with
1> [
1> _Elem=char,
1> _Traits=std::char_traits<char>,
1> _Alloc=std::allocator<char>
1> ]
运行以下代码时：
std::string arrString[3] = {"dir","cd ..","dir"};
int i;
LPWSTR cmd =L"cmd";
for(i=0; i<3; i++)
{
STARTUPINFO info={sizeof(info)};
PROCESS_INFORMATION processInfo;
if (CreateProcess(cmd, arrString[i].c_str, NULL, NULL, TRUE, 0, NULL, NULL, &info, &processInfo))
{
::WaitForSingleObject(processInfo.hProcess, INFINITE);
CloseHandle(processInfo.hProcess);
CloseHandle(processInfo.hThread);
}
我是否朝着正确的方向前进？
编辑：
std::string arrString[3] = {"cmd","cmd","cmd"};
int i;
LPWSTR cmd =L"cmd";
for(i=0; i<3; i++)
{
STARTUPINFO info={sizeof(info)};
PROCESS_INFORMATION processInfo;
vector<wchar_t> cmdline(arrString[i].begin(), arrString[i].end());
CreateProcessW(cmd, &cmdline[0], NULL, NULL, TRUE, 0, NULL, NULL, &info, &processInfo);
::WaitForSingleObject(processInfo.hProcess, INFINITE);
CloseHandle(processInfo.hProcess);
CloseHandle(processInfo.hThread);
}
