PrinterName (PSZ) - input

Address of the name of the printer that queries the active code page and font.

CodePage (PUSHORT) - output

Address of the active code page that returns the specified printer and System File Number.

FontID (PUSHORT) - output

Address of the active Font ID number that returns the specified printer and System File Number.

SFN (USHORT) - input

System File Number of the requester. The SFN is passed as a parameter in the monitor packet.

Reserved (ULONG) - input

Return Code

rc (USHORT) - return

Return values are:

• 10 Invalid printer name as input.
• 13 Received code page request when code page switcher not initialized.
• 16 Received request for system file number not in the system file number table.

Remarks

DosPFSQueryAct is intended for use only by applications that replace the spooler as a print monitor and that do code page switching. Other applications should use printer IOCTLs to manipulate printer code page switching.

DosPFSQueryAct is located in SPOOLCP.DLL (not in DOSCALLS.LIB) and requires an import statement in the module definition file. Refer to the IBM Operating System/2 Version 1.2 Building Programs, Module Definition File Statements section for information regarding the import statement.
