proc_unref(D3)

NAME
     proc_unref - release a reference to a process

SYNOPSIS
     #include <sys/ddi.h>
     void proc_unref(void *pref);

   Arguments
     pref      Identifier obtained by a previous call to proc_ref(D3).

DESCRIPTION
     The proc_unref function can be used to release a reference to a process
     identified by the parameter pref.

   Return Values
     None

USAGE
     There must be a matching call to proc_unref for every previous call to
     proc_ref(D3).

     Processes can exit even though they are referenced by drivers.  In this
     event, reuse of pref will be deferred until all driver references are
     given up.

   Level
     Base or Interrupt.

   Synchronization Constraints
     Does not sleep.

     Driver-defined basic locks, read/write locks, and sleep locks may be held
     across calls to this function.
