DCE Threads Exceptions
DCE Threads provides two ways to obtain information about the results of a threads call. One way is specified by the POSIX P1003.4a (pthreads) draft standard - status values are returned to the thread. DCE Threads also gives the programmer an alternative to status values. This is provided by the exception-returning interface, which is an extension to the basic POSIX functionality. Exceptions enable routines to ignore status returns when other parts of the program are handling errors.
