void highvideo(void); 

Description 

Selects high-intensity characters. 

highvideo selects high-intensity characters by setting the high-intensity bit of the currently selected foreground color. 

This function does not affect any characters currently onscreen, but does affect those displayed by functions (such as cprintf) that perform direct video, text mode output after highvideo is called.

None. 

Example  

#include <conio.h>
int main(void)
{
clrscr();
lowvideo();
cprintf("Low Intensity text\r\n");
highvideo();
gotoxy(1,2);
cprintf("High Intensity Text\r\n");
return 0;
}
