Notes on common parameters:
handle is the connected endpoint that will be used for I/O.
buf is the buffer to write from or receive into.
len is the number of bytes to transfer.
The timeout parameter in the following methods indicates how long to blocking trying to transfer data. If timeout == 0, then the call behaves as a normal send/recv call, i.e., for blocking sockets, the call will block until action is possible; for non-blocking sockets, EWOULDBLOCK will be returned if no action is immediately possible.
If timeout != 0, the call will wait until the relative time specified in *timeout elapses.
The "_n()" I/O methods keep looping until all the data has been transferred. These methods also work for sockets in non-blocking mode i.e., they keep looping on EWOULDBLOCK . timeout is used to make sure we keep making progress, i.e., the same timeout value is used for every I/O operation in the loop and the timeout is not counted down.
The return values for the "*_n()" methods match the return values from the non "_n()" methods and are specified as follows:
- On complete transfer, the number of bytes transferred is returned.
- On timeout, -1 is returned,
errno == ETIME . - On error, -1 is returned,
errno is set to appropriate error. - On
EOF , 0 is returned, errno is irrelevant.
On partial transfers, i.e., if any data is transferred before timeout / error / EOF , bytes_transferred> will contain the number of bytes transferred.
Methods with iovec parameter are I/O vector variants of the I/O operations.
Methods with the extra flags argument will always result in send getting called. Methods without the extra flags argument will result in send getting called on Win32 platforms, and write getting called on non-Win32 platforms.
