DosMonWrite

This call moves a filtered data record from the monitor's private data area into the monitor's output buffer.

Syntax

DosMonWrite (BufferO, DataBuffer, Bytecnt)

Parameters

BufferO (PBYTE) - input

Address of the monitor output buffer.

DataBuffer (PBYTE) - input

Address of the monitor's private data area that contains a filtered data record of length Bytecnt. DosMonWrite moves this filtered data record into the monitor's output buffer.

Bytecnt (USHORT) - input

Number of bytes in the data record.

Return Code

rc (USHORT) - return

Return code descriptions are:

• 0 - NO_ERROR
• 8 - ERROR_NOT_ENOUGH_MEMORY
• 379 - ERROR_MON_INVALID_PARMS
• 384 - ERROR_MON_DATA_TOO_LARGE

Remarks

For a detailed description of the use of this call see the chapter "Character Device Monitors" in the IBM Operating System/2 Version 1.2 I/O Subsystems And Device Support Volume 1.

Example Code

C Binding

#define INCL_DOSMONITORS

PBYTE            BufferO;       /* Monitor output buffer */
PBYTE            DataBuffer;    /* Buffer from which records are taken */
USHORT           Bytecnt;       /* Number of bytes */

USHORT           rc;            /* return code */
