Writing Output From a Channel Program

The C runtime library stdout input-output destination may be usurped by the SDK, depending upon the context under which a channel program has been invoked. As such, programs that will operate as channels should use the mtaLog() routine to write information to their log file. Such programs should never write output directly to stdout or stderr or other generic I/O destinations, such as Pascal’s output, or FORTRAN’s default output logical unit. There’s no telling where such output might go: it might go to the Job Controller’s log file, it might even go down a network pipe to a remote client or server.


Note –

The channel log file is a different file from the MTA log file. The mtaLog() and mtaAccountingLogClose() are unrelated routines.
