May be equal to print_display or video_display, or may be a new display connection that the caller should close when done. .TP .I selection_return Returns the selection atom for which a PDM selection should be made. .TP .I type_return Returns the type for the PDM Selection Protocol property the caller is expected to create. .TP .I format_return Returns the format for the PDM Selection Protocol property the caller is expected to create. .TP .I data_return Returns the data set for the PDM Selection Protocol property the caller is expected to create. The caller is expected to XFree the data when finished. .TP .I nelements_return Returns the number of elements for the PDM Selection Protocol property the caller is expected to create. .SH DESCRIPTION .LP This request returns a zero status if an error occurred, non-zero otherwise. XpGetPdmStartParams is a convenience routine used to construct the necessary property information and selection display connection information needed to initiate a PDM Selection per the "PDM Selection Protocol". Once the information is constructed, the caller is responsible for the creation of a property, the generation of a SelectionRequest, the receipt of a SelectionNotify event, and the receipt of a ClientMessage event, as described in the PDM Selection Protocol. When finished, the caller is expected to free data using XFree. XpGetPdmStartParams returns zero if an error occurred, else non-zero. If an error occurs all .I other_return values are undefined. Setting the environment variable XPDMSELECTION causes XpGetPdmStartParams to use an alternate selection name. If not set, the selection name .I PDM_MANAGER is used. Setting the environment variable XPDMDISPLAY causes XpGetPdmStartParams to locate the selection on an alternate X Server. If not set, .I selection_display_return is set equal to .I print_display. If XPDMDISPLAY is set to one of the keywords "print" or "video", .I selection_display_return is set to .I print_display or .I video_display, respectively. If XPDMDISPLAY is set to a valid DISPLAY-style string, .I selection_display_return may be set, as appropriate, to one of .I print_display, .I video_display, or to a new display connection opened from within XpGetPdmStartParams. Only in the single case where a new display connection is made should the caller close .I selection_display_return using XCloseDisplay. When XpGetPdmStartParams is called, the caller's locale (see XpSetLocaleHinter) is included in the information as a "hint" to the Print Dialog Manager (PDM). If supported by the implementation, the PDM will use the hint to display dialogs more appropriately labeled for the locale of the client. If the Print Dialog Manager cannot understand the hint, the PDM will choose a default. Note that the locale of the print attributes that the PDM will subsequently access, will already have been determined when the client called XpCreateContext. The environment variables XPDMDISPLAY and XPDMSELECTION are re-read each time XpGetPdmStartParams is called. .SH "SEE ALSO" .BR XpCreateContext (3Xp), .BR XpSetLocaleHinter (3Xp)
