In addition to the standard POSIX functions defined above, the -following non-POSIX functions are defined in the FILEIO package.
int ioctl( int fd, CYG_ADDRWORD com, CYG_ADDRWORD data ); -int select( int nfd, fd_set *in, fd_set *out, fd_set *ex, struct timeval *tv); |
int socket( int domain, int type, int protocol); -int bind( int s, const struct sockaddr *sa, unsigned int len); -int listen( int s, int len); -int accept( int s, struct sockaddr *sa, socklen_t *addrlen); -int connect( int s, const struct sockaddr *sa, socklen_t len); -int getpeername( int s, struct sockaddr *sa, socklen_t *len); -int getsockname( int s, struct sockaddr *sa, socklen_t *len); -int setsockopt( int s, int level, int optname, const void *optval, - socklen_t optlen); -int getsockopt( int s, int level, int optname, void *optval, - socklen_t *optlen); -ssize_t recvmsg( int s, struct msghdr *msg, int flags); -ssize_t recvfrom( int s, void *buf, size_t len, int flags, - struct sockaddr *from, socklen_t *fromlen); -ssize_t recv( int s, void *buf, size_t len, int flags); -ssize_t sendmsg( int s, const struct msghdr *msg, int flags); -ssize_t sendto( int s, const void *buf, size_t len, int flags, - const struct sockaddr *to, socklen_t tolen); -ssize_t send( int s, const void *buf, size_t len, int flags); -int shutdown( int s, int how); |
The precise behaviour of these functions depends mainly on the - functionality of the underlying filesystem or network stack to - which they are applied. -
