Remarks

DosPFSActivate 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.

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

Return values are:

• Code page not available.
  
• Font ID not available.
  
• Code page switcher internal error.
