Constructors

this

this()

Constructor.

Members

Functions

bind

int bind(sockaddr_un* address)

Assigns a local address to this socket. socket() must have been called previously.

connect

int connect(sockaddr_un* address)

Connects this socket the specified address and port. socket() must have been called previously.

formatInfo

void formatInfo(char[] buf, bool io_error)

Formats information about the socket into the provided buffer.

socket

int socket(int type)

Creates a socket endpoint for communication and sets this.fd to the corresponding file descriptor.

Inherited Members

From ISocket

SocketFlags

alias SocketFlags = .SocketFlags

Flags supported by accept4().

fd

int fd;

File descriptor. Set by socket()/accept() and reset by close() and clear(). Should be modified otherwise only in special situations.

close_in_destructor

bool close_in_destructor;

If true, the destructor will call close(). Enabled by socket()/accept() on success, disabled by close() and socket()/accept() on failure. Should be modified otherwise only in special situations.

suppress_sigpipe

bool suppress_sigpipe;

If true, send() and therefore write() are requested not to send SIGPIPE on errors when this socket is stream oriented (e.g. TCP) and the other end breaks the connection.

in_addrlen

socklen_t in_addrlen;

Address struct (sin_addr/sin6_addr) length.

~this

~this()

Destructor. Calls close() if indicated by close_in_destructor.

fileHandle

Handle fileHandle()

Required by ISelectable.

error

int error()

Calls getsockopt(SOL_SOCKET, SO_ERROR) to obtain the current error code for this socket.

error

int error(ISelectable socket)

Calls getsockopt(SOL_SOCKET, SO_ERROR) to obtain the current error code for the socket referred to by fd.

socket

int socket(int domain, int type, int protocol)

Creates a socket endpoint for communication and sets this.fd to the corresponding file descriptor.

bind

int bind(sockaddr* local_address)

Assigns a local address to this socket. This socket needs to have been created by socket().

accept

int accept(ISelectable listening_socket, sockaddr* remote_address, socklen_t addrlen, SocketFlags flags)

Accepts a connection from a listening socket and sets this.fd to the accepted socket file descriptor.

accept

int accept(ISelectable listening_socket, SocketFlags flags)

Accepts a connection from a listening socket and sets this.fd to the accepted socket file descriptor.

accept

int accept(ISelectable listening_socket, bool nonblocking)

Accepts a connection from a listening socket and sets this.fd to the accepted socket file descriptor.

connect

int connect(sockaddr* remote_address)

Connects this socket the specified address and port.

listen

int listen(int backlog)

listen() marks this socket as a passive socket, that is, as a socket that will be used to accept incoming connection requests using accept().

shutdown

int shutdown(int how)

The shutdown() call causes all or part of a full-duplex connection on the socket to be shut down.

getsockopt

ssize_t getsockopt(int level, int optname, void[] dst)

Obtains the value of a socket option, writing the value data to dst.

getsockoptVal

ssize_t getsockoptVal(int level, int optname, T val)

Calls getsockopt() to obtain the value of a socket option.

setsockopt

int setsockopt(int level, int optname, const(void)[] src)

Sets the value of a socket option, using the value data in src. The actual value data type and length depends on the particular option.

setsockoptVal

int setsockoptVal(int level, int optname, T val)

Calls setsockopt() to sets the value of a socket option to val.

write

ssize_t write(const(void)[] src)

Calls send() to send as many src bytes as possible.

send

ssize_t send(const(void)[] src, int flags)

Sends as many src bytes as possible to the remote.

recv

ssize_t recv(void[] dst, int flags)

Receives dst.length bytes from the remote but at most as possible with one attempt.

getsockname

int getsockname(sockaddr* local_address, socklen_t addrlen)

Obtains the local socket address.

getpeername

int getpeername(sockaddr* remote_address, socklen_t addrlen)

Obtains the remote socket address.

close

int close()

Closes the socket and resets the file descriptor, address and port.

clear

void clear()

Resets the file descriptor, address and port. Called from close(), should be called otherwise only in special situations.

formatInfo

void formatInfo(char[] buf, bool io_error)

Formats information about the socket into the provided buffer.
