SYNOPSIS

DESCRIPTION

15       The  function  parses *name and tries to find a videomode corresponding
16       on it.  *name is parsed case insensitive and should be either an  inte‐
17       ger string just giving a mode number or consist of a capital G followed
18       by the amount of x pixels, followed by a lower case x, followed by  the
19       amount  of y pixels, followed by a lower case x.  Finally the number of
20       different colors is appended. Here the shortcuts 32K,64K,16M, and  16M4
21       are  used for 32768, 65536, and 16777216 are used. The last refers also
22       to 16777216 which are store in 4 bytes (highest  address  byte  unused)
23       for easier screen access.
24
25       For unsupported values or the string "PROMPT" the value -1 is returned.
26       Also a irritating error message is printed to stdout. This is used dur‐
27       ing  parsing the SVGALIB_DEFAULT_MODE environment variable. Probably it
28       should not be used for anything else.
