Considerations

The following considerations apply to the use of the PRINTINIT[2] procedure:



PRINTINIT[2] should not be used by a perusal process. A print process operates

with, and under the control of, the supervisor, while a perusal process operates on

its own.



Before calling PRINTINIT[2], a print process must have a file open to the

supervisor with nowait I/O and a sync depth of, at most, 1.



PRINTINIT[2] must be followed at some point by a call to AWAITIO[X].



The print-control-buffer returned by PRINTINIT[2] is used by the

supervisor to send messages to the print process. The print process should never

alter this buffer except with calls to the print procedures.



Usually, PRINTINIT[2] is called only once by a print process.
