DosPFSInit

This call allows the Font Switcher to initialize code page and font switching for a specified printer.

Syntax

DosPFSInit (CPHdw, FontFileName, PrinterType, PrinterName, Instances, Reserved)

Parameters

CPHdw (PUSHORT) - input

Address of the pointer list, in the following format, that specifies the hardware code page and fonts on the printer.

0 - Number of definitions that follow. DWord 1/N - Code page number (1st Word of DWord) and Font ID (2nd Word of DWord) for each hardware font in order corresponding to the hardware code page and font selection numbers. (For example, the first code page and font ID value corresponds to the default hardware font 0, the second, to hardware font 1, the third, to hardware font 2, and so on. If the default hardware font is not known, 0 should be specified for the default code page and font).

FontFileName (PSZ) - input

Address of the pathname of the font file of the specified printer that initiates the code page and font switching.

PrinterType (PSZ) - input

Address of the printer type ID.

PrinterName (PSZ) - input

Address of the name of the printer that initiates code page and font switching.

Instances (USHORT) - input

Maximum number of different instances of use tracking code page and font switching. This value is advisory for the Font Switcher allocating enough resources for the specified number of instances being tracked.

Reserved (ULONG) - input

Reserved must be set to zero.

Return Code

rc (USHORT) - return

Return values are:

• Code page switcher already initialized
• User entered too many ROMs in DEVINFO, initialization continued with the rest
• Wrong or missing font file ID
• Code page switcher internal error
• 10 Invalid printer name as input
• 11 Printer type input does not match that in font file
• 12 Could not get storage for control blocks
• 14 Could not open font file during initialization
• 17 Switcher reports too many system file number entries
• 19 I/O error reading font file control sequence section
• 20 I/O error reading font file header
• 21 I/O error reading font file font definition block
• 22 Some fonts bad due to error in font file, initialization continued.

Remarks

DosPFSInit 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.

DosPFSInit is located in SPOOLCP.DLL (not 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.
