CSX_MAKEDEVICENODE 9F "Jul 19, 1996"
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 structure.

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_MakeDeviceNode() 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 information. The meanings of the fields in the devnode_desc_t structure are identical to the parameters of the same name to the ddi_create_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 information. 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.
