#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);
Solaris DDI Specific (Solaris DDI)
ch
Client handle returned from csx_RegisterClient(9F).
dn
Pointer to a make_device_node_t or remove_device_node_t structure.
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.
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.
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.
These functions may be called from user or kernel context.
