+.SH NAME
+vga_gettextmoderegs, vga_settextmoderegs \- get/set the vga state used in text mode
+.SH SYNOPSIS
+
+.B "#include <vga.h>"
+
+.BI "void vga_gettextmoderegs(void *state);"
+.br
+.BI "void vga_settextmoderegs(void *state);"
+
+.SH DESCRIPTION
+The functions gives access to the buffer where svgalib saves the vga state which is use when
+the kernel displays text on the SVGA.
+This is used by the
+.BR restoretextmode "(1), "
+.BR savetextmode "(1), and "
+.BR textmode "(1)"
+utilities to restore a possibly screwed console.
+
+The buffer currently occupies 385 bytes. It can't do any harm to make it substantially larger
+to allow for future enhancements.
