vga_getmodenumber(3)          Svgalib User Manual         vga_getmodenumber(3)


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.
