ShellExecute C


What is the syntax to run a program in C?
I want my C program to execute another program
I am a noob at C/C++ programming,
My friend said something about
ShellExecute(handle, NULL, path_to_folder, NULL, NULL, SW_SHOWNORMAL)

But I don't know what that is... how would I execute a program
named hi ???

Thanx

Do a search for exec in the programming forum :)
Or a man system.

Cheers,

Well its been a while since college but aren't C programs just executables? If so you would just do:

./hi

if the C programs name was hi.

Oh you mean in the source code itself? This is a programming question right? Ummm...well I'm no c programming expert but I do remember a function that might work for this.

int ok;

int main()
{
ok=system("programname")
}

I'm not sure if thats the exact syntax but I know the system function passes the argument directly to the command line.

Thanx, what header is that in?
When I compile my program, I geth
hi.c: In function `int main()':
hi.c:11: `ok' undeclared (first use this function)
hi.c:11: (Each undeclared identifier is reported only once for each function it
appears in.)

#ifdef HAVE_CONFIG_H
#include <config.h>
#endif

#include <iostream.h>
#include <stdlib.h>
#include <shellapi.h>

int main()
{
ok =system("emacs");


return EXIT_SUCCESS;
}




Thanx
