.SH DESCRIPTION
.sp
.LP
\fBcsx_MakeDeviceNode()\fR and \fBcsx_RemoveDeviceNode()\fR are
Solaris-specific extensions to allow the client to request that device nodes in
the filesystem are created or removed, respectively, on its behalf.
.SH STRUCTURE MEMBERS
.sp
.LP
The structure members of \fBmake_device_node_t\fR are:
.sp
.in +2
.nf
uint32_t        Action;         /* device operation */
uint32_t        NumDevNodes;    /* number of nodes to create */

The structure members of \fBremove_device_node_t\fR are:
.sp
.in +2
.nf
uint32_t       Action;          /* device operation */
uint32_t       NumDevNodes;     /* number of nodes to remove */
devnode_desc_t *devnode_desc;   /* description of device nodes */
.fi
.in -2

.sp
.LP
The structure members of \fBdevnode_desc_t\fR are:
.sp
.in +2
.nf
char           *name;           /* device node path and name */
int32_t        spec_type;       /* device special type (block or char) */

.sp
.LP
The \fBAction\fR field is used to specify the operation that
\fBcsx_MakeDeviceNode()\fR and \fBcsx_RemoveDeviceNode()\fR should perform.
.sp
.LP
The following \fBAction\fR values are defined for \fBcsx_MakeDeviceNode()\fR:
.sp
.ne 2
.na
\fBCREATE_DEVICE_NODE\fR
.ad
.RS 22n
Create \fBNumDevNodes\fR minor nodes
.RE

.sp
.LP
The following \fBAction\fR values are defined for \fBcsx_RemoveDeviceNode()\fR:
.sp
.ne 2
.na
\fBREMOVE_DEVICE_NODE\fR
.ad
.RS 27n
Remove \fBNumDevNodes\fR minor nodes
.RE

.sp
.ne 2
.na
\fBREMOVE_ALL_DEVICE_NODES\fR
.ad
.RS 27n
Remove all minor nodes for this client
.RE

.sp
.LP
For \fBcsx_MakeDeviceNode()\fR, if the \fBAction\fR field is:
.sp
.ne 2
.na
\fB\fBCREATE_DEVICE_NODE\fR \fR
.ad
.RS 23n
The \fBNumDevNodes\fR field must be set to the number of minor devices to
create, and the client must allocate the quantity of \fBdevnode_desc_t\fR
structures specified by \fBNumDevNodes\fR and fill out the fields in the
\fBdevnode_desc_t\fR structure with the appropriate minor node information. The
meanings of the fields in the \fBdevnode_desc_t\fR structure are identical to
the parameters of the same name to the \fBddi_create_minor_node\fR(9F) \fBDDI
\fRfunction.
.RE

.sp
.LP
For \fBcsx_RemoveDeviceNode()\fR, if the \fBAction\fR field is:
.sp
.ne 2
.na
\fB\fBREMOVE_DEVICE_NODE\fR \fR
.ad
.RS 28n
The \fBNumDevNodes\fR field must be set to the number of minor devices to
remove, and the client must allocate the quantity of \fBdevnode_desc_t\fR
structures specified by \fBNumDevNodes\fR and fill out the fields in the
\fBdevnode_desc_t\fR structure with the appropriate minor node information. The
meanings of the fields in the \fBdevnode_desc_t\fR structure are identical to

.RS 28n
The \fBNumDevNodes\fR field must be set to \fB0\fR and the \fBdevnode_desc_t\fR
structure pointer must be set to \fINULL\fR. All device nodes for this client
will be removed from the filesystem.
