csx_ModifyWindow(9F)	 Kernel Functions for Drivers	  csx_ModifyWindow(9F)

NAME
       csx_ModifyWindow - modify window attributes

SYNOPSIS
       #include <sys/pccard.h>

       int32_t csx_ModifyWindow(window_handle_t wh, modify_win_t *mw);

INTERFACE LEVEL
       Solaris DDI Specific (Solaris DDI)

PARAMETERS
       wh	Window handle returned from csx_RequestWindow(9F).

       mw	Pointer to a modify_win_t structure.

DESCRIPTION
       This  function  modifies	 the  attributes  of a window allocated by the
       csx_RequestWindow(9F) function.

       Only some of the window attributes or the access	 speed	field  may  be
       modified	 by this request. The csx_MapMemPage(9F) function is also used
       to set the offset into PC Card memory to be mapped into	system	memory
       for paged windows.  The csx_RequestWindow(9F) and csx_ReleaseWindow(9F)
       functions must be used to change the window base or size.

STRUCTURE MEMBERS
       The structure members of modify_win_t are:

       uint32_t	      Attributes;	   /* window flags */
       uint32_t	      AccessSpeed;	   /* window access speed */

       The fields are defined as follows:

       Attributes      This field is bit-mapped and defined as follows:

		       WIN_MEMORY_TYPE_CM

			   Window points to Common Memory area.	 Set  this  to
			   map the window to Common Memory.

		       WIN_MEMORY_TYPE_AM

			   Window points to Attribute Memory area. Set this to
			   map the window to Attribute Memory.

		       WIN_ENABLE

			   Enable Window. The client must set this  to	enable
			   the window.

		       WIN_ACCESS_SPEED_VALID

			   AccessSpeed	valid.	The  client must set this when
			   the AccessSpeed field has a value that  the	client
			   wants set for the window.

       AccessSpeed     The  bit	 definitions  for this field use the format of
		       the extended speed byte of the Device ID tuple. If  the
		       mantissa	 is  0	(noted	as  reserved in the PC Card 95
		       Standard), the lower bits are a binary code  represent‐
		       ing  a  speed from the list below. Numbers in the first
		       column are  codes;  items  in  the  second  column  are
		       speeds.

		       0	Reserved: do not use

		       1	250 nsec

		       2	200 nsec

		       3	150 nsec

		       4	100 nsec

		       5 - 7	Reserved: do not use

		       It  is  recommended  that  clients use the csx_Convert‐
		       Speed(9F)  function   to	  generate   the   appropriate
		       AccessSpeed  values rather than manually perturbing the
		       AccessSpeed field.

RETURN VALUES
       "small and bold">CS_SUCCESS     Successful operation.

       CS_BAD_HANDLE		       Window handle is invalid.

       CS_NO_CARD		       No PC Card in socket.

       CS_BAD_OFFSET		       Error getting/setting  window  hardware
				       parameters.

       CS_BAD_WINDOW		       Error  getting/setting  window hardware
				       parameters.

       CS_BAD_SPEED		       AccessSpeed is invalid.

       CS_UNSUPPORTED_FUNCTION	       No PCMCIA hardware installed.

CONTEXT
       This function may be called from user or kernel context.
