.SH SYNOPSIS

.B "#include <vga.h>"

.BI "int vga_getdefaultmode(void);"

.SH DESCRIPTION
Returns the default graphics mode number from the
.B SVGALIB_DEFAULT_MODE
environment variable; -1 if undefined. The
environment variable can either be a mode number or a mode name. See
.BR vga_setmode (3)
for a list of predefined return values and their meaning. The mode names which can be used
in the environment are those used by
.BR vga_getmodename (3)
and
.BR vga_getmodenumber (3).

Whenever your application has no special need for a given mode you should always try to
honour this setting for consistency among svgalib applications.
