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.
