ARGUMENTS    [Toc]    [Back]

       Specifies  a  pointer to the complex lock structure, lock.
       The lock 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.

DESCRIPTION    [Toc]    [Back]

       The  lock_done routine releases a lock that was previously
       asserted by one of the following  complex  lock  routines:
       lock_read,  lock_try_read, lock_try_write, and lock_write.

NOTES    [Toc]    [Back]

       You must hold the lock  on  the  resource  before  calling
       lock_done.
