mongoc_stream_writev()

Synopsis

ssize_t
mongoc_stream_writev (mongoc_stream_t *stream,
                      mongoc_iovec_t  *iov,
                      size_t           iovcnt,
                      int32_t          timeout_msec);

Parameters

stream	A mongoc_stream_t.
iov	A vector of mongoc_iovec_t.
iovcnt	The number of items in iov.
timeout_msec	The number of milliseconds to block before indicating failure, or 0 for non-blocking. Negative values indicate the default timeout.

The mongoc_stream_writev() function shall perform a write to a mongoc_stream_t. It's modeled on the API and semantics of writev(), though the parameters map only loosely.

Returns

The number of bytes written on success, or -1 upon failure and errno is set.
