getchar()

hey everyone!
got another problem here.
how would i use the getchar() in a prompt:
Press any key to continue

the way i did it was to define a char variable named ch
and then wrote

Code:

char ch
...
ch = getchar();
printf("Press any key to continue");
getchar():

if you press enter it exits, but if you type anything else it displays it on the screen and you still have to press enter after.

is there anyway to make the program continue without displaying the result to the screen and so the user can press any key they want?

thanks

vga_getch

vga_getch(3)							Svgalib User Manual						      vga_getch(3)

NAME

       vga_getch - wait for a key

SYNOPSIS

       #include <vga.h>

       int vga_getch(void);

DESCRIPTION

       waits for a key press just like getchar(3) would.

       For a non blocking check for a keypress use vga_getkey(3) or use vga_waitevent(3) if you want to wait for several events to occur at once.
