Sdevregister -- register SCSI peripheral drivers

Synopsis

   #include <sys/devreg.h>
   
   static dreg;
   Sdevregister(dreg)
   SDEVREG *dreg;

Description

Sdevregister is called by SCSI device drivers at initialization of I/O (from the init(D2osdi) entry point routine) to register a SCSI device structure Sdevreg pointed to by dreg. This allows the kernel to keep track of all active SCSI peripheral drivers.

If not already registered, the device is registered at the back, otherwise Sdevregister returns without performing any action.

Arguments

dreg: Pointer to the Sdevreg(D4osdi) structure.

Return values

None.
