|
|
.SH NAME
|
|
vga_waitretrace \- wait for vertical retrace.
|
|
.SH SYNOPSIS
|
|
|
|
.B "#include <vga.h>"
|
|
|
|
.BI "void vga_waitretrace(void);"
|
|
|
|
.SH DESCRIPTION
|
|
Wait for vertical retrace, that is when the video beam goes dark and returns from the
|
|
bottom line to the top line. Useful to synchronize animation with
|
|
monitor refresh.
|
|
|
|
However, Linux is a multiuser OS, thus some time might have passed already when the
|
|
function returns. Also, not all cards support this in all modes (or with more or
|
|
less good results).
