List of all members.

Detailed Description

helper methods for dealing with sockets. Use instead of direct methods for portability.

Definition at line 53 of file SockUtil.h.

Static Public Member Functions
static void	init ()
	automatically called. Added for WinSock, which needs to be initialized
static void	setNonblock (socket_t s)
	Make socket s be non-blocking.
static void	fillSockAddr (const std::string &host, uint16_t port, struct sockaddr_in &sa) throw (AddressException)
	fill contents of the sockaddr_in from the host and port
static void	fillSockAddr (uint32_t addr, uint16_t port, struct sockaddr_in &sa)
	fill contents of the sockaddr_in from the addr and port
static void	fillSockAddr (const SockAddr &addr, struct sockaddr_in &sa)
	fill a sockaddr_in from a SockAddr
static SockAddr	getSockAddr (const std::string &hostname) throw (AddressException)
	return a SockAddr from a hostname
static int	getErrno ()
	Use instead of the variable "errno".
static bool	errorWouldBlock (int err=-1)
	Check of the err (or getErrno()) is because call would block (EAGAIN, EWOULDBLOCK, EINTR, or EINPROGRESS).
static bool	errorInterrupted (int err=-1)
	Check if the err (or getErrno()) is interrupted (EINTR).
static bool	errorBadF (int err=-1)
	Check if the err (or getErrno()) is a bad file descriptor (EBADF).
static bool	errorConnFail (int err=-1)
	Check if the err (or getErrno()) is a connection failure (ECONNABORTED or EPROTO).
static bool	errorTransient (int err=-1)
	Check if the err (or getErrno()) is a transient system error (ENFILE, EMFILE, ENOBUFS, ENOMEM).
static bool	errorNotConnected (int err=-1)
	Check if the err (or getErrno()) is not connected (ENOTCONN or EINVAL).
Static Public Attributes
static const SockAddr	NULL_MSOCKADDR = SockAddr()
	convenience object for a "null" SockAddr
static const MaceAddr	NULL_MACEADDR = MaceAddr()
	convenience object for a "null" MaceAddr
static const std::string	NAT_STRING = "(NAT)"
	reference "NAT" string (presently "(NAT)"
