 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. 

 Return values are: 

 9         Code page switcher internal error.
