(Windows only solution)
By modifying the example: https://learn.microsoft.com/en-us/windows/win32/procthread/creating-processes
for C++:
#include <iostream>
#include <Windows.h>
int main(int argc, char* argv[])
{
if (argc != 2)
{
std::cout << "Usage: " << argv[0] << " [cmdline]\n";
return EXIT_FAILURE;
}
STARTUPINFOA si = {sizeof(si)};
PROCESS_INFORMATION pi = {};
// Start the child process.
if (!CreateProcessA(nullptr, // No module name (use command line)
argv[1], // Command line
nullptr, // Process handle not inheritable
nullptr, // Thread handle not inheritable
false, // Set handle inheritance to FALSE
0, // No creation flags
nullptr, // Use parent's environment block
nullptr, // Use parent's starting directory
&si, // Pointer to STARTUPINFO structure
&pi)) // Pointer to PROCESS_INFORMATION structure
{
std::cout << "CreateProcess failed (" << GetLastError() << ").\n";
return EXIT_FAILURE;
}
// Wait until child process exits.
//WaitForSingleObject(pi.hProcess, INFINITE);
// Close process and thread handles.
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
return EXIT_SUCCESS;
}
