install_vga_console(9r)
NAME
  install_vga_console - Graphics: Installs a VGA console as the system
  console

SYNOPSIS
  int install_vga_console(
	  struct controller *ctlr );

ARGUMENTS
  ctlr
      Specifies a pointer to the driver's controller structure.

DATA STRUCTURES
  The install_vga_console routine accesses the driver's controller structure
  defined in /usr/sys/include/io/common/devdriver.h.

DESCRIPTION
  The install_vga_console routine lets you register the VGA console with the
  Workstation Subsystem. If you are implementing a VGA-class card or a
  compound card that uses a VGA chip for the console, you can call this
  routine instead of writing your own VGA graphics console driver.  You call
  the install_vga_console routine from the device driver's console_attach
  routine.

RETURN VALUES
  If successful, the install_vga_console routine returns 0 (zero) or a
  positive integer. If unsuccessful, it returns -1.

EXAMPLES
  The myvga_console_attach routine calls install_vga_console as follows to
  install the VGA console as the system console:

       int
       myvga_console_attach(struct controller *ctlr)
       {

       .
       .
       .

	 status = install_vga_console(ctlr);

       .
       .
       .

       }
