 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
illumos DDI Specific (illumos 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
illumos-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.
