For that, you'll need to know more than just the "existance" of the file,
you'll also want to make sure that the previous job is done writing the
file.

i.e. you don't want to grab it, process it, and delete it if the user is
still adding data to the file.

The opendir(), readdir() APIs allow you to open up a directory name
and read through a list of files in that directory.   I know I've written
samples of this and posted it to the lists before...

go to:
       http://archive.midrange.com

and search the MIDRANGE-L and RPG400-L lists for opendir() and readdir().

Then, take a look at the fcntl() API, which allows you to get & set
locking info for a file.  You'll need that to make sure that other jobs
are finished with the file.
