Chapter 44. APIs
select (int nfd,
fd_set ∗ in, fd_set ∗ out, fd_set ∗ ex,
struct timeval ∗ tv);
does not support the restart.
The additional API:
int
cyg_select_with_abort (int nfd,
fd_set ∗ in, fd_set ∗ out, fd_set ∗ ex,
struct timeval ∗ tv)
behaves exactly as select() with the additional feature that a call to
void cyg_select_abort (void)
will cause all threads waiting in any cyg_select_with_abort() call to cease waiting and continue execution.
