NAME
mongoc_stream_readv - mongoc_stream_readv()

SYNOPSIS

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

PARAMETERS

    •   stream: A mongoc_stream_t.

    •   iov: A vector of mongoc_iovec_t.

    •   iovcnt: The number of items in iov.

    •   min_bytes: The minimum number of bytes to read or failure will be indicated.

    •   timeout_msec: A timeout in milliseconds, or 0 to indicate non-blocking. A negative value with use the default timeout.

This function is identical to mongoc_stream_read() except that it takes a mongoc_iovec_t to perform gathered I/O.

RETURNS

>= 0 on success, -1 on failure and errno is set.
