.SH "DESCRIPTION"
.PP
Register a miscellaneous device with the kernel\&. If the minor number is set to
\fBMISC_DYNAMIC_MINOR\fR
a minor number is assigned and placed in the minor field of the structure\&. For other cases the minor number requested is used\&.
.PP
The structure passed is linked into the kernel and may not be destroyed until it has been unregistered\&. By default, an
\fBopen\fR
syscall to the device sets file\->private_data to point to the structure\&. Drivers don\*(Aqt need open in fops for this\&.
.PP
A zero is returned on success and a negative errno code for failure\&.
