send

Arguments

:: Connection

Connection

-> ByteString

Slice of a buffer

-> IO (Either (SendException Uninterruptible) ())

Send a slice of a buffer. If needed, this calls POSIX send repeatedly until the entire contents of the buffer slice have been sent.

receiveExactly

Arguments

:: Connection

Connection

-> Int

Exact number of bytes to receive

-> IO (Either (ReceiveException Uninterruptible) ByteString)

Receive a number of bytes exactly equal to the length of the buffer slice. If needed, this may call recv repeatedly until the requested number of bytes have been received.

receiveOnce

Arguments

:: Connection

Connection

-> Int

Maximum number of bytes to receive

-> IO (Either (ReceiveException Uninterruptible) ByteString)

Receive at most the specified number of bytes. This only makes multiple calls to POSIX recv if EAGAIN is returned. It makes at most one recv call that successfully fills the buffer.

receiveBetween

Arguments

:: Connection

Connection

-> Int

Minimum number of bytes to receive

-> Int

Maximum number of bytes to receive

-> IO (Either (ReceiveException Uninterruptible) ByteString)

Receive a number of bytes that is between the inclusive lower and upper bounds. If needed, this may call recv repeatedly until the minimum requested number of bytes have been received.
