Description 

 

SetFont 

This function sets the current font used in OutTextXY(), OutText() and OutChar() functions. 

 

OutChar 

This function outputs a character from the current graphic cursor position. OutChar() uses the current active font set with SetFont(). 

 

OutText 

This function outputs a string of characters starting at the current graphic cursor position. The string must be terminated by a line feed or zero. For Non-Blocking configuration, OutText() may return control to the program due to display device busy status. When this happens zero is returned and OutText() must be called again to continue the outputting of the string. For Blocking configuration, this function always returns a 1. OutText() uses the current active font set with SetFont(). 

 

OutTextXY 

This function outputs a string of characters starting at the given x, y position. The string must be terminated by a line feed or zero. For Non-Blocking configuration, OutTextXY() may return control to the program due to display device busy status. When this happens zero is returned and OutTextXY() must be called again to continue the outputting of the string. For Blocking configuration, this function always returns a 1. OutTextXY() uses the current active font set with SetFont().
