Classes
struct	xdr::sock_t
	Abstract away the type of a socket (for windows). More...
struct	std::hash< xdr::sock_t >
struct	xdr::delete_addrinfo
	A deleter to use std::unique_ptr with addrinfo structures (which must be freed recursively). More...
class	xdr::unique_sock
	Self-closing socket. More...

Namespaces
	xdr
	Most of the xdrpp library is encapsulated in the xdr namespace.

Typedefs
using	xdr::unique_addrinfo = std::unique_ptr< addrinfo, delete_addrinfo >
	Automatically garbage-collected addrinfo pointer.

Functions
bool	xdr::sock_eagain ()
	Returns true if the most recent (socket) error is a temporary error, such as EAGAIN, EWOULDBLOCK, or EINTR. More...
const char *	xdr::sock_errmsg ()
	Last socket error message (strerror(errno) on POSIX).
void	xdr::throw_sockerr (const char *)
	Throw a system_error exception for the last socket error.
ssize_t	xdr::read (sock_t s, void *buf, std::size_t count)
ssize_t	xdr::write (sock_t s, const void *buf, std::size_t count)
ssize_t	xdr::readv (sock_t s, const struct iovec *iov, int iovcnt)
ssize_t	xdr::writev (sock_t s, const struct iovec *iov, int iovcnt)
void	xdr::close (sock_t s)
void	xdr::set_nonblock (sock_t s)
	Set the O_NONBLOCK flag on a socket. More...
void	xdr::set_close_on_exec (sock_t s)
	Set the close-on-exec flag of a file descriptor. More...
sock_t	xdr::accept (sock_t s, sockaddr *addr, socklen_t *addrlen)
	Wrapper around accept for sock_t.
void	xdr::create_selfpipe (sock_t ss[2])
	Create a socket (or pipe on unix, where both are file descriptors) that is connected to itself. More...
const std::error_category &	xdr::gai_category ()
	Category for system errors dealing with DNS (getaddrinfo, etc.).
unique_addrinfo	xdr::get_addrinfo (const char *host, int socktype=SOCK_STREAM, const char *service=nullptr, int family=AF_UNSPEC)
	Wrapper around getaddrinfo that returns a garbage-collected xdr::unique_addrinfo. More...
void	xdr::get_numinfo (const sockaddr *sa, socklen_t salen, std::string *host, std::string *serv)
	Return printable versions of numeric host and port number.
unique_sock	xdr::tcp_connect1 (const addrinfo *ai, bool ndelay=false)
	Try connecting to the first addrinfo in a linked list.
unique_sock	xdr::tcp_connect (const addrinfo *ai)
	Try connecting to every addrinfo in a list until one succeeds.
unique_sock	xdr::tcp_connect (const unique_addrinfo &ai)
unique_sock	xdr::tcp_connect (const char *host, const char *service, int family)
unique_sock	xdr::tcp_listen (const char *service="0", int family=AF_UNSPEC, int backlog=5)
	Create bind a listening TCP socket.

Variables
constexpr sock_t	xdr::invalid_sock {}
