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

NAME
       csx_MakeDeviceNode,  csx_RemoveDeviceNode  -  create  and  remove minor
       nodes on behalf of the client

SYNOPSIS
       #include <sys/pccard.h>

       int32_t csx_MakeDeviceNode(client_handle_t ch, make_device_node_t *dn);

       int32_t csx_RemoveDeviceNode(client_handle_t  ch,  remove_device_node_t
       *dn);

INTERFACE LEVEL
       Solaris DDI Specific (Solaris DDI)

PARAMETERS
       ch	Client handle returned from csx_RegisterClient(9F).

       dn	Pointer to a make_device_node_t or remove_device_node_t struc‐
		ture.

DESCRIPTION
       csx_MakeDeviceNode() and	 csx_RemoveDeviceNode()	 are  Solaris-specific
       extensions  to  allow  the  client  to request that device nodes in the
       filesystem are created or removed, respectively, on its behalf.

STRUCTURE MEMBERS
       The structure members of make_device_node_t are:

       uint32_t	       Action;	       /* device operation */
       uint32_t	       NumDevNodes;    /* number of nodes to create */
       devnode_desc_t  *devnode_desc;  /* description of device nodes */

       The structure members of remove_device_node_t are:

       uint32_t	      Action;	       /* device operation */
       uint32_t	      NumDevNodes;     /* number of nodes to remove */
       devnode_desc_t *devnode_desc;   /* description of device nodes */

       The structure members of devnode_desc_t are:

       char	      *name;	       /* device node path and name */
       int32_t	      spec_type;       /* device special type (block or char) */
       int32_t	      minor_num;       /* device node minor number */
       char	      *node_type;      /* device node type */

       The Action field is used to specify the operation that csx_MakeDeviceN‐
       ode() and csx_RemoveDeviceNode() should perform.

       The following Action values are defined for csx_MakeDeviceNode():

       CREATE_DEVICE_NODE

	   Create NumDevNodes minor nodes

       The following Action values are defined for csx_RemoveDeviceNode():

       REMOVE_DEVICE_NODE

	   Remove NumDevNodes minor nodes

       REMOVE_ALL_DEVICE_NODES

	   Remove all minor nodes for this client

       For csx_MakeDeviceNode(), if the Action field is:

       CREATE_DEVICE_NODE

	   The NumDevNodes field must be set to the number of minor devices to
	   create, and the client must allocate the quantity of devnode_desc_t
	   structures  specified by NumDevNodes and fill out the fields in the
	   devnode_desc_t structure with the appropriate minor	node  informa‐
	   tion.  The  meanings	 of the fields in the devnode_desc_t structure
	   are identical to the parameters of the same name  to	 the  ddi_cre‐
	   ate_minor_node(9F) DDI function.

       For csx_RemoveDeviceNode(), if the Action field is:

       REMOVE_DEVICE_NODE

	   The NumDevNodes field must be set to the number of minor devices to
	   remove, and the client must allocate the quantity of devnode_desc_t
	   structures  specified by NumDevNodes and fill out the fields in the
	   devnode_desc_t structure with the appropriate minor	node  informa‐
	   tion.  The  meanings	 of the fields in the devnode_desc_t structure
	   are	identical  to  the  parameters	of  the	 same  name   to   the
	   ddi_remove_minor_node(9F) DDI function.

       REMOVE_ALL_DEVICE_NODES

	   The	NumDevNodes  field  must  be  set  to 0 and the devnode_desc_t
	   structure pointer must be set to NULL. All device  nodes  for  this
	   client will be removed from the filesystem.

RETURN VALUES
       CS_SUCCESS		       Successful operation.

       CS_BAD_HANDLE		       Client handle is invalid.

       CS_BAD_ATTRIBUTE		       The  value  of one or more arguments is
				       invalid.

       CS_BAD_ARGS		       Action is invalid.

       CS_OUT_OF_RESOURCE	       Unable to create or remove device node.

       CS_UNSUPPORTED_FUNCTION	       No PCMCIA hardware installed.

CONTEXT
       These functions may be called from user or kernel context.
