Network.Unexceptional.MutableBytes

sockets convert a reception length of zero to an non-standard EOI error code. Datagram reception functions do not do this.

Stream Sockets

receive

Arguments

:: Socket

-> MutableBytes RealWorld

Slice of a buffer

-> IO (Either Errno Int)

Receive bytes from a socket. Receives at most N bytes, where N is the size of the buffer. Returns the number of bytes that were actually received.

receiveInterruptible

Arguments

:: TVar Bool

Interrupt

-> Socket

-> MutableBytes RealWorld

Slice of a buffer

-> IO (Either Errno Int)

receiveExactly

Arguments

:: Socket

-> MutableBytes RealWorld

Length is the exact number of bytes to receive, must be greater than zero.

-> IO (Either Errno ())

Blocks until an exact number of bytes has been received.

receiveExactlyInterruptible

Arguments

:: TVar Bool

-> Socket

-> MutableBytes RealWorld

Length is the exact number of bytes to receive, must be greater than zero.

-> IO (Either Errno ())

Datagram Sockets

receiveFromInterruptible

Arguments

:: TVar Bool

-> Socket

-> MutableBytes RealWorld

Slice of a buffer

-> IO (Either Errno (Int, SockAddr))

Receive bytes from a socket. Receives at most N bytes, where N is the size of the buffer. Returns the number of bytes that were actually received.
