Infoprint XT passes
data to the transform input application exit by using streams, and
the application exit passes data back to Infoprint XT. The
streams are:
- fd0 (STDIN)
- Infoprint XT uses
standard input to pass the original Xerox job to the transform input
application exit.
- fd1 (STDOUT)
- The transform input application exit must use standard output
to pass the Xerox job back to Infoprint XT. The
Xerox job can be in its original format, or it might contain modifications
that the application exit made. The function of the transform input
application exit determines the format.
- fd2 (STDERR)
- Infoprint XT captures
anything that is written to standard error. Infoprint XT writes
the information from standard error to the aioxlxie.lst file
in the working directory for the job. If the conversion process
fails to produce AFP output, Infoprint XT includes
the standard error information on the error sheet for the job.
Note: The transform input application exit must always use unbuffered
input/output (I/O).
