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.
