NAME

XdSetErrorHandler − specify a user error handler for screen geometry change

SYNOPSIS

        XdSetErrorHandler(error_proc)
        int (∗error_proc)() ;

error_proc
Specifies the users error handler

USAGE

Use XdSetErrorHandler to specify a function to be called whenever the low level graphics library detects that the screen geometry has changed. 

The term screen geometry refers to the windows that are visible on screen, their size, and their location.  If the screen geometry changes while your application is using the low level graphics library, it invalidates drawing commands that have been produced.  The user-specified error procedure is called whenever that geometry changes.  When the user’s specified error handler is called the application should redraw all the windows that are currently open for direct graphics.
