NAME    [Toc]    [Back]

       lock - General: Contains complex lock-specific information

SYNOPSIS    [Toc]    [Back]

       The lock data structure is an opaque data structure;  that
       is,  its associated members are referenced and manipulated
       by the operating system and not by the user of the complex
       lock  mechanism.  Therefore,  this  reference page omits a
       description of the lock data structure's  associated  members.

DESCRIPTION    [Toc]    [Back]

       The lock data structure is the complex lock structure that
       contains complex lock-specific information. A kernel  module
  writer  using  the  complex  lock  method  declares a
       pointer to a lock data structure and passes its address to
       the associated lock routines.

NOTES    [Toc]    [Back]

       The  header  file  <lock.h>  shows typedef statements that
       assign the alternate name lock_data_t for the complex lock
       structure  and  lock_t  for  a pointer to the complex lock
       structure.
