VIS_PUTCMAP
The VIS_PUTCMAP
ioctl command
establishes the console color map. The terminal emulator calls this function
to set up the color map of the kernel. The vis_cmap structure
is shown in the following code. This structure only applies to 8-bit color
indexed mode.
struct vis_cmap { int index; /* Index into colormap to start updating */ int count; /* Number of entries to update */ unsigned char *red; /* List of red values */ unsigned char *green; /* List of green values */ unsigned char *blue; /* List of blue values */ };
The VIS_PUTCMAP
ioctl command
is similar to the FBIOPUTCMAP
command.
The VIS_PUTCMAP
command is specific
to the frame buffer terminal-emulator compatible console code.
