With execvp you need an argv array already built. So a program like:

Code:

#include "stdlib.h"  /** vb is eating my angle brackets **/
main(argc,argv)
int argc;
char **argv;
{
      execvp(*++argv, argv);
}

will simply pass its arguments to execvp.

With execlp you do stuff like:
execlp("echo", "echo", "one", "two", NULL);
