Chapter 41. APIs
Standard networking
The APIs for the standard networking calls such as socket() , recv() and so on, are in header files relative to
the top-level include directory, within the standard subdirectories as conventionally found in /usr/include . For
example:
install/include/arpa/tftp.h
install/include/netinet/tcpip.h
install/include/sys/socket.h
install/include/sys/socketvar.h
install/include/sys/sockio.h
Enhanced Select()
The network stack supports an extension to the standard select semantics which allows all threads that are waiting
to be restarted even if the select conditions are not satisfied.
The standard select() API:
int
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.
