Prototype

void textbackground(int newcolor);

Description

Selects new text background color.

Note: Do not use this function in Win32 GUI applications.

textbackground selects the background color. This function works for functions that produce output in text mode directly to the screen. newcolor selects the new background color. You can set newcolor to an integer from 0 to 7, or to one of the symbolic constants defined in conio.h. If you use symbolic constants, you must include conio.h.

Once you have called textbackground, all subsequent functions using direct video output (such as cprintf) will use newcolor. textbackground does not affect any characters currently onscreen.

The following table lists the symbolic constants and the numeric values of the allowable colors:

BLACK	0
BLUE	1
GREEN	2
CYAN	3
RED	4
MAGENTA	5
BROWN	6
LIGHTGRAY	7

Return Value

None.

Example

Copy Code

#include <conio.h>
int main(void)
{
   int i, j;
   clrscr();
   for (i=0; i<9; i++)
   {
       for (j=0; j<80; j++)
          cprintf("C");
       cprintf("\r\n");
       textcolor(i+1);
       textbackground(i);
   }
   return 0;
}
