Hi all, I'm trying to get the exit code of a program
I want to exec in a python script in a portable manner.
I've read that both os.system and os.spawnl are not a
portable solution.
I tried the os.popen() function and I got the program's exit
code with the close() method.
p=os.popen("return_a_exit_code.sh")

What is the difference between using exit(n) and return n in main(), if
any? I know that exit(n) is a function that exits and return n exits via a
return value, but is there any reason to specify one rather than the
other? Thanks!

I notice in my stdlib.h:
#define EXIT_FAILURE 1 /* Failing exit status. */
#define EXIT_SUCCESS 0 /* Successful exit status. */
Are these definitions dictated by the standard? I've seen them used often
in
this group so I assume they are.
If so, are there any other standard defined return values that I could use

As far as I can tell, the standard has defined three portable return
codes from function main() (0, EXIT_SUCCESS, EXIT_FAILURE). Personally,
on all platforms I have worked with, EXIT_SUCCESS is, "#define
EXIT_SUCCESS 0" and EXIT_FAILURE is, "#define EXIT_FAILURE 1". I have,
however, been told that a few platforms define the two in reverse...

I have heard that return -1 is not portable. So what would be the answer
to portability in this case? What about exit(0) and exit (-1) or exit (1)?
Or would it be best to stick with C's macros, hence:
exit(EXIT_FAILURE)
exit (EXIT_SUCCESS)

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
