5.5 DECthreads Exceptions and Definitions

Table 5-1 lists the DECthreads exceptions and briefly explains the meaning of each exception.

Exception names beginning with the prefix pthread_ or cma_ are raised as the result of something happening internal to the DECthreads facility and are not meant to be raised by user code. Exceptions beginning with pthread_exc_ are generic and belong to the exception facility and/or the underlying system.

See Section E.4 for a list and descriptions of the cma interface exceptions.
