运行这段代码时出现异常:
STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory(&si, sizeof(si));
si.cb = sizeof(si);
ZeroMemory(&pi, sizeof(pi));
CreateProcess(NULL, L"program.dat", NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi);
// Wait until child process exits.
WaitForSingleObject( pi.hProcess, INFINITE );
// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
我在 WaitForSingleObject 上得到异常。
谢谢:)
最佳答案
在 documentation 中尽可能清楚地说明::
The Unicode version of this function, CreateProcessW, can modify the contents of this string. Therefore, this parameter cannot be a pointer to read-only memory (such as a const variable or a literal string). If this parameter is a constant string, the function may cause an access violation.
您的 L"program.dat" 符合此规则。将字符串复制到某个 WCHAR 变量中并改为传递它。
