XDisplayName()							XDisplayName()

Name
  XDisplayName	–  report  the display name (when connection to a display
  fails).

Synopsis
  char *XDisplayName(string)
	char *string;

Arguments
  string    Specifies the character string.

Returns
  The display name string.

Description
  XDisplayName() is normally used to report the name of the  display  the
  program  attempted  to  open	with  XOpenDisplay().	This is necessary
  because X error handling begins only after the connection to the server
  succeeds.

  If  a	 NULL  string  is  specified, XDisplayName() looks in the DISPLAY
  environment variable and returns the display name  that  the	user  was
  requesting.  Otherwise, XDisplayName() returns its own argument.

  For more information, see Volume One, Chapter 3, Basic Window Program.
