NAME

       vga_getmodenumber - return a number for the given video mode

SYNOPSIS

       #include <vga.h>

       int vga_getmodenumber(char *name);

DESCRIPTION

       The  function  parses  *name  and tries to find a videomode corresponding on it.  *name is
       parsed case insensitive and should be either an integer string just giving a  mode  number
       or  consist of a capital G followed by the amount of x pixels, followed by a lower case x,
       followed by the amount of y pixels, followed by a lower case x.   Finally  the  number  of
       different colors is appended. Here the shortcuts 32K,64K,16M, and 16M4 are used for 32768,
       65536, and 16777216 are used. The last refers also to 16777216 which are store in 4  bytes
       (highest address byte unused) for easier screen access.

       For  unsupported values or the string "PROMPT" the value -1 is returned. Also a irritating
       error message is printed to stdout. This is used during parsing  the  SVGALIB_DEFAULT_MODE
       environment variable. Probably it should not be used for anything else.

EXAMPLE

       vga_getmodenumber("G640x480x256") returns 10.
