Abstract:
|
|||
|
|
|
|||
|
|
Contains functions for creating and deleting Events on which the
|
|||
|
|
messenger threads will wait. The events get set if either data is
|
|||
|
|
received, or a new name is added to the name table. These routines
|
|||
|
|
were originally written for OS/2 semaphores.
