I've been string to learn linux programming this weekend.
I've picked a bad place to start http://www.overthewire.org/
I've had a hard time finding different ways to start a process.
What I really need is a way to start a process and be able to pass it the 'int argc, char *argv[]'
values.
can this be done with execl() ?

the limits provided by time, complexity and tolerance.

And you didn't do man execl because why?
Edit: And if you had read further down the page and wanted to literally pass argv, rather than a bunch of args:The const char *arg0 and subsequent ellipses in the execl(), execlp(),
and execle() functions can be thought of as arg0, arg1, ..., argn.
Together they describe a list of one or more pointers to null-terminated
strings that represent the argument list available to the executed pro-
gram. The first argument, by convention, should point to the file name
associated with the file being executed. The list of arguments must be
terminated by a NULL pointer.
The execv(), execvp(), and execvP() functions provide an array of point-
ers to null-terminated strings that represent the argument list available
to the new program. The first argument, by convention, should point to
the file name associated with the file being executed. The array of
pointers must be terminated by a NULL pointer.
sorry i'm running a livecd and the man files are incomplete. Thx for the post. I got what i needed from your reply.Code:bt vortex # man execl No manual entry for execl

What makes you think I didn't type "man execl" into the little box in the top right-hand corner of my browser?

Perhaps the problem is not knowing what the function is called in the first place. How would you know what to search for?
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
