_gtSetBlink()
 Toggle asterisk (*) interpretation in color strings between blinking and
 background intensity
------------------------------------------------------------------------------
 C Prototype

     #include "gt.api"
     ERRCODE _gtSetBlink(
                          BOOL bBlink
                        )

 Arguments

     bBlink toggles the meaning of the asterisk (*) character in a color
     string.  Specifying TRUE causes the asterisk to mean blinking and FALSE
     causes it to mean high intensity background.  The default is TRUE.

 Returns

     _gtSetBlink() returns zero if successful.  Any other value indicates an
     error.

 Description

     _gtSetBlink() toggles the blinking/background intensity attribute.  When
     you call _gtSetBlink() with bBlink equal to TRUE, you can make
     characters written to the screen blink by including an asterisk (*) in
     the color string passed to _gtSetColorStr().  When you call
     _gtSetBlink() with bBlink equal to FALSE, the asterisk (*) causes the
     background color to be intensified instead.  Thus, blinking and
     background intensity attributes are not available at the same time.

     Note:  This function is meaningful only on IBM PC or compatible
     computers with CGA, EGA, or VGA display hardware.

 Examples

     .  This example enables high intensity backgrounds:

        #include "gt.api"

        .
        .
        .
           _gtSetBlink( FALSE )
        .
        .
        .
