|GPDLFO (fdid, csid, font)|
Use GPDLFO to delete a font definition from the specified font directory. If the specified font definition does not exist in the font directory, this subroutine has no effect.
If the specified character set/font is currently active to any workstation, it remains active to the workstation until the application deactivates it. However, it is still deleted from the font directory.
See Appendix A. "Character Set and Font Identifiers" for more information.
