### display_message

`void display_message(char * msg)`
`void display_message(char * msg, char * title)`
`void display_message(char * msg, char * title, int flag)`

Writes msg in the Xcoral Messages Box. If title is given, it is written at the top of the window, otherwise previous title is cleared. If flag is not null, a separator is inserted before msg (i.e. the string '>>>' and a return are inserted , thus the message will be displayed on a new line); when flag is not given its value is 0.
