.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

The \fBAction\fR field is used to specify the operation that \fBcsx_MakeDeviceNode()\fR and \fBcsx_RemoveDeviceNode()\fR should perform.

.RS 23n
.rt  
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.
