pszPortName (PSZ) - input

Port name.

Following is an example of a port name:
LPT1


This will be a locally defined port name.

pfnBaseProtXlateCmd (PFN) - input

Base protocol converter address for ProtXlateCmd routine.

This is NULL unless the protocol converter is an extension to the base protocol converter. If not NULL, the extension protocol converter can call the base converter at this address to let the base converter process the command.

pInData (PVOID) - input

Command sequence for printer.

On entry, this field contains the BIDI software protocol-specific command sequence received from the printer.

cbInData (ULONG) - input

Length of information in pInData, in bytes.

pAlertInfo (PVOID) - in/out

Alert information buffer.

This field receives a PDALERTINFO data structure. See Data Types for details on this data structure.

pOutData (PVOID) - output

Return buffer.

If PD_ALERT is set, this returns a PRTALERT structure. See BIDI_WAIT_ALERT(8016h) in BIDI Command Structures and Command Flow for more information and Data Types for details on this data structure.

If PD_ALERT is not set, nothing is returned in this buffer.

pcbOutData (PULONG) - output

Points to the length of the output buffer.

On entry, this is set to the length of the output buffer passed in. On exit, it is updated with the length of the PRTALERT structure data copied into pOutData.

rc (ULONG) - returns

Return codes.
• Success

• ERROR_NOT_ENOUGH_MEMORY)
  Not enough memory to satisfy request.
  87(ERROR_INVALID_PARAMETER)
  An invalid parameter was specified; most likely an invalid buffer pointer was given.
  211(ERROR_INFO_NOT_AVAIL)
  The caller set PD_NEXTALERT. However, the protocol converter does not have any more alerts to return for the previous data passed to SplProtXlateCmd for the port.
  234(ERROR_MORE_DATA)
  Part of the information requested was returned, but there was not enough room for all the data. *pcbOutData contains the size of buffer needed to retrieve all the query response data.
  2123(NERR_BufTooSmall)
  No information was returned because the output buffer was too small. *pcbOutData contains the size of buffer needed to retrieve all the query response data.
