SYNOPSIS

          ssize_t
          mongoc_stream_write (mongoc_stream_t *stream,
                               void *buf,
                               size_t count,
                               int32_t timeout_msec);

PARAMETERS

       • stream: A mongoc_stream_t <>.

       • buf: The buffer to write.

       • count: The number of bytes to write.

       • timeout_msec:  The  number  of  milliseconds  to wait before failure, a timeout of 0 will not block. If
         negative, use the default timeout.

       The mongoc_stream_write() <> function shall perform a write to a mongoc_stream_t <>. It's modeled on  the
       API and semantics of write(), 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  mongoc_stream_write()  <> function returns the number of bytes written on success. It returns -1 and
       sets errno upon failure.
