[windows c]CreateProcess

#include <windows.h>
#include <stdio.h>
#include <tchar.h>

void _tmain( VOID )
{
    STARTUPINFO si;
    PROCESS_INFORMATION pi;
    LPTSTR szCmdline=_tcsdup(TEXT("MyChildProcess"));

    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof(si);
    ZeroMemory( &pi, sizeof(pi) );

    // Start the child process.
    if( !CreateProcess( NULL,   // No module name (use command line)
       szCmdline,      // Command line
       NULL,           // Process handle not inheritable
       NULL,           // Thread handle not inheritable
       FALSE,          // Set handle inheritance to FALSE
       0,              // No creation flags
       NULL,           // Use parent‘s environment block
       NULL,           // Use parent‘s starting directory
       &si,            // Pointer to STARTUPINFO structure
       &pi )           // Pointer to PROCESS_INFORMATION structure
       )
    {
       printf( "CreateProcess failed (%d)./n", GetLastError() );
       return;
    }

    // Wait until child process exits.
    WaitForSingleObject( pi.hProcess, INFINITE );

    // Close process and thread handles.
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
}

以上是msdn官方实例。

想要返回结果，GetExitCodeProcess是个办法。
