XpGetPrinterList(3Xp) XPRINT FUNCTIONS XpGetPrinterList(3Xp) NAME
XpGetPrinterList - Retrieves a list of all printers supported on an X Print Server. SYNOPSIS
cc [ flag... ] file... -lXp [ library... ] #include <X11/extensions/Print.h> XPPrinterList XpGetPrinterList ( display, printer_name, list_count_return ) Display *display; char *printer_name; int *list_count_return; ARGUMENTS
display Specifies a pointer to the Display structure; returned from XOpenDisplay. printer_name Specifies the name of the printer for which information is desired. If NULL, then information is returned for all printers associ- ated with the server. list_count_return Returns the number of printers in the list. DESCRIPTION
XpGetPrinterList returns a list of printer records where each record describes a printer supported by the X Print Server, or NULL if any errors occur. If printer_name is NULL, then a list of all printers supported is returned. If printer_name is non-NULL, only print records matching printer_name are returned, and if no records match printer_name , then NULL is returned. printer_name is a COMPOUND_TEXT string, and the name and desc fields in the returned list will be in COMPOUND_TEXT (note, ISO 8859-1 (Latin-1) is a proper subset of COMPOUND_TEXT, so can be used directly). If printer_name is in a code-set that the X Print Server cannot convert (into its operating code-set), then the X Print Server may fail to locate the requested printer. If printer_name is NULL, then all printer names, regardless of their code-set, can be returned, leaving the task of specific printer recognition up to the caller. When XpGetPrinterList is called, the caller's locale (see XpSetLocaleHinter) is included in the request as a "hint" to the X Print Server. If supported by the implementation, the X Print Server will use the hint to locate a localized description for each printer in the list. If the X Print Server cannot understand the hint, the X Print Server will choose a default. The returned printer list can be freed by calling XpFreePrinterList. The XPPrinterList structure defined in <X11/extensions/Print.h> contains: typedef struct { char *name; /* name */ char *desc; /* localized description */ } XPPrinterRec, *XPPrinterList; DIAGNOSTICS
