XpSetContext(3Xp)              XPRINT FUNCTIONS              XpSetContext(3Xp)




NAME

       XpSetContext  -  Sets or unsets a print context with the specified dis-
       play connection to the X Print Server.


SYNOPSIS

             cc [ flag... ] file... -lXp [ library... ]
             #include <X11/extensions/Print.h>

       void XpSetContext ( display, print_context )
             Display *display;
             XPContext print_context;


ARGUMENTS

       display
              Specifies a pointer to  the  Display  structure;  returned  from
              XOpenDisplay.

       print_context
              A pre-existing print context on the same X Server.


DESCRIPTION

       XpSetContext  sets the print context for a display connection. All sub-
       sequent print operations that do not explicitly take a print context-id
       (for  example,  XpStartJob)  on display will use and act upon the print
       context set by this call, until the print context  is  unset  or  XpDe-
       stroyContext is called. The print context can be set and used on multi-
       ple jobs, if not destroyed.

       If print_context is None, XpSetContext will  unset  (disassociate)  the
       print  context previously associated with display. If there was no pre-
       viously associated print context, no action is taken.  The  content  of
       the formerly associated print context is not affected by this call, and
       other display connections may continue to use the print context.

       Since font capabilities can vary from printer to printer,  XpSetContext
       may modify the list of available fonts (see XListFonts) on display, and
       the actual set of usable fonts (see XLoadFont). A unique combination of
       fonts  may  be  available  from  within a given print context; a client
       should not assume that all the fonts available when no print context is
       set will be available when a print context is set.

       When a print context is set on a display connection, the default behav-
       ior of ListFonts and ListFontsWithInfo is to list all of the fonts nor-
       mally associated with the X print server (i.e. fonts containing glyphs)
       as well as any internal printer fonts defined for the printer. The  xp-
       listfonts-modes  attribute is provided so that applications can control
       the behavior of ListFonts and ListFontsWithInfo and is  typically  used
       to show just internal printer fonts.  Using only internal printer fonts
       is useful for performance reasons; the glyphs associated with the  font
       are contained within the printer and do not have to be downloaded.

       If  the value of xp-listfonts-modes includes xp-list-glyph-fonts, List-
       Fonts and ListFontsWithInfo will include all of the fonts available  to
       the  server  that have glyphs associated with them. If the value of xp-
       listfonts-modes includes xp-list-internal-printer-fonts, then ListFonts
       and ListFontsWithInfo will include all of the fonts defined as internal
       printer fonts.

       When the print context is unset  or  XpDestroyContext  is  called,  the
       available fonts on display revert back to what they were previously.


DIAGNOSTICS

       XPBadContext   A  valid print context-id has not been set prior to mak-
                      ing this call.
