July 06, 2003 D system call | ||||
---|---|---|---|---|

I have a program I would like to execute from within another! How would I accomplish this in D? Here's the equivalent code in C++: #include <cstdlib> int main() { std::system("some_program"); } |

Thanks, that does the trick!
However, since I'd much rather speak my native tongue! Is there a way to say this natively in "D"?

Anyway, if you don't want to use the C standard library and you're running Windows you can use CreateProcess instead, but using it is very awkward. |

Posted in reply to Dario | In C world this function would be in <process.h>, not <file.h>, but perhaps execute() could alternatively take a file object instead of a pathname. It's pretty important to have this; depending on the OS command line syntax makes you system dependant.
