NAME

       lock - General: Contains complex lock-specific information

SYNOPSIS

       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  associ-
       ated members.

DESCRIPTION

       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

       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.
