In "form.c" you probably have registered a call back function for the
input field. Might look like this:
obj = fl_add_input (...);
fl_set_object_callback(obj,Input_cb,0);
So when you are done and hit return in the input field, the call back
function (I called it here Input_cb) will be executed.
You might also have a file "form_cb.c" where you have
void Input_cb (FL_OBJECT *ob, long data ) {
/* received return from the input */
if ( data == 0 ) {
printf ( " %s\n",fl_get_input(ob));
}
/* You can use the argument (data) to distinguish between
different input fields that share the same call back function
*/
}
Hope this helps.
