==== Description of showerrorbox ==== 
<code c>
The showerrorbox function is available in the winbgim implementation of
BGI graphics. You do not need to include conio.h; just include
graphics.h. The function opens a windows error message box with the
specified message (or a standard message if the message parameter is
NULL). The message box waits for the user to click on OK button before
showerrorbox returns.
