Data Structures for Drivers                ddiidevicecookie(9S)



NAME
     ddiidevicecookie - device interrupt cookie

SYNOPSIS
     #include 
     #include 


INTERFACE LEVEL
     Solaris  DI  specific  (Solaris  DI).  This  interface  is
     obsolete.  Use  the  new  interrupt interfaces referenced in
     Intro(9F). Refer to Writing Device Drivers for more informa-
     tion.

DESCRIPTION
     The ddiidevicecookiet structure contains interrupt prior-
     ity  and  interrupt  vector  information  for a device. This
     structure is useful for  devices  having  programmable  bus-
     interrupt  levels.  ddiaddintr(9F)  assigns  values to the
     ddiidevicecookiet structure members.

STRUCTURE MEMBERS
       ushort   idevvector;      /* interrupt vector */
       ushortt  idevpriority;    /* interrupt priority */



     The idevvector field contains the interrupt  vector  number
     for   vectored   bus   architectures  such  as  VMEbus.  The
     idevpriority field  contains  the  bus  interrupt  priority
     level.
