NAME

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

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(3) except that it takes a mongoc_iovec_t
       to perform gathered I/O.

RETURNS

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