 @subheading DESCRIPTION:
 
-The @code{rtems_task_set_affinity} routine is used to set the
-@code{affinity.set} field of the thread control object associated
-with @code{id}.  This value controls the @code{cpuset} that the task can
-execute on.
+Sets the processor affinity set for the task specified by @code{cpuset}.  A set
+bit in the affinity set means that the task can execute on this processor and a
+cleared bit means the opposite.
 
 @subheading NOTES:
 
-NONE
+None.
