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.
