man XpSelectInput (3): Specifies which X Print events, from the specified print context,

SYNOPSIS

void XpSelectInput ( display, context, event_mask )

      Display *display;

      XPContext context;

      unsigned long event_mask;

ARGUMENTS

display: Specifies a pointer to the Display structure; returned from XOpenDisplay.
context: Specifies the print context from which to select events.
event_mask: Specifies the event mask. This mask is the bitwise OR one or more of the valid events mask bits (see below).

DESCRIPTION

XpSelectInput selects which X Print events from the specified print context the client is interest in. The X Print Events are generated from a current print context, and not from a window as is the case with XSelectInput.

STRUCTURES

The bits for event_mask are defined in <X11/extensions/Print.h>:

    #define XPNoEventMask               0
    #define XPPrintMask                 (1L<<0)
    #define XPAttributeMask             (1L<<1)

The resulting events are defined in <X11/extensions/Print.h>:

    #define XPPrintNotify               0
    #define XPAttributeNotify           1

DIAGNOSTICS

BadValue: The value specified for event_mask is not valid.
XPBadContext: The specified print context is not valid.
