c wrapper file
hello all! i feel like what i am trying to do is easy i am just unsure of how to do it.
what i want to do is create a c-wrapper file to run through a series of commands so that once the first program is complete pro/e will run. here are the commands i would type
1.) nsga2
2.) proewildfire trail2.txt
now with the nsga2 there are a lot of header files associated with it...do i have to include <> all of those?
thanks for all of your help!!!

This sounds like it would more appropriately be a shell script than a C program.

okay so i have tried to create a simple c program...it compiles and runs but there is no output...for example:
/*this C-wrapper file will execute first the nsga2 executable file and then run pro/e using the trail.txt file*/
#include <stdlib.h>
#include <stdio.h>
main()
{
printf("Files in Directory are:\n");
execl("/home/edog.1/jlm661 /nsga/GA/" ,"ls", "-l",0);
//printf("The following output describes the NSGA optimization process:\n");
//execl("/home/edog.1/jlm6 61/nsga/GA /","nsga2" , 0);
//printf("Pro/E will now run using the trail.txt file:n");
//execl("/home/edog.1/", "proewildfire trail.txt", 0);
}
i am just trying to show the list of the files contained in my folder, but when i run the executable nothing but the line i printed comes up. what am i donig wrong? i probably look like a newbie but i am so bear with me :)

Hi jlm661,
execl() is NOT the same as system(). system() spawns another task and executes the command string that you pass to it. execl() replaces the current task with whatever the execl() is supposed to do.
Change the calls to execl() to system(). You'll also have to build the command string into a single string.
