## Presentation Device Driver Reference for OS/2

### GreEscape DEVESC_STARTDOC - Remarks

The driver continues to spool or print data until it receives DEVESC_ENDDOC . This ensures that documents longer than one page are not interspersed with other jobs.

Because DEVESC_STARTDOC is not mandatory at the API, it cannot be assumed that an application (when opening a DC for printing) will pass DEVESC_ STARTDOC to the presentation driver. In this case, the presentation driver must initialize a spool file with no name or a journal file in the CompleteOpenDC handling routine. If this is done, the presentation driver should set a flag so that initialization is not repeated if DEVESC_STARTDOC is received. Notice that a handling routine is required for DEVESC_STARTDOC to save the specified document name in the DC instance data.

When this function call is issued for an OD_QUEUED device, the presentation driver must start the recording of data into the spool file by calling SplStdStart. It should also call SplQmStartDoc to pass the name of the spool file to the visual spooler. See SplStdStart and SplQmStartDoc.

This escape code is metafiled but not recorded.
