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.

       WARNING:
          The  "default  timeout"  indicated  by  a  negative  value  is  both  unspecified and unrelated to the
          documented default values for *TimeoutMS URI options.  To  specify  a  default  timeout  value  for  a
          *TimeoutMS URI option, use the MONGOC_DEFAULT_* constants defined in mongoc-client.h.

RETURNS

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