#!N #!N Functional Details The task to be added is defined
by the following parameters: #!N #!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18*
#!F-adobe-times-bold-r-normal--18* proc #!EF #!EF #!I50 #!N A pointer to a function
that performs the task. It takes one argument of type #!F-adobe-times-bold-r-normal--18*
Pointer #!EF . #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* arg #!EF #!EF
#!I50 #!N A pointer to an argument block. #!N #!I0 #!N
#!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* size #!EF #!EF #!I50 #!N The size of the
argument block in bytes. If #!F-adobe-times-bold-r-normal--18* size #!EF is nonzero, the
argument block is copied. Otherwise, the value of #!F-adobe-times-bold-r-normal--18* arg #!EF
is passed to #!F-adobe-times-bold-r-normal--18* proc #!EF without copying, which is useful
for passing integers or Objects. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* work
#!EF #!EF #!I50 #!N The estimated amount of time required by
the task in arbitrary units. #!I0 #!N #!N #!N #!N Tasks
are executed, in parallel if possible, by #!F-adobe-times-bold-r-normal--18* DXExecuteTaskGroup #!EF .
Executing a task consists of calling #!F-adobe-times-bold-r-normal--18* (*proc)(arg) #!EF . To
facilitate load balancing, tasks are executed in order of decreasing work
estimates. Once #!F-adobe-times-bold-r-normal--18* DXExecuteTaskGroup #!EF has been called, additional tasks can
be created only from other tasks in the current task Group,
and they are run as soon as possible, without regard to
#!F-adobe-times-bold-r-normal--18* work #!EF or the status of the original tasks. #!N
#!N Return Value Returns #!F-adobe-times-bold-r-normal--18* OK #!EF or returns #!F-adobe-times-bold-r-normal--18* ERROR
#!EF and sets an error code. #!N #!N See Also #!F-adobe-times-bold-r-normal--18*
