65 Instead, the new lwp will execute a function provided by the

111 Two parameters are provided so that storage for both parent
112 and child can be specified separately.
113 Setting any of these to NULL causes the respective tid not to be copied out.
119 specifies the new lwp's CPU affinity mask.
121 means no special CPU affinity settings.
