mongoc_stream_writev - mongoc_stream_writev()

ssize_t
mongoc_stream_writev (mongoc_stream_t *stream,


                      mongoc_iovec_t *iov,


                      size_t iovcnt,


                      int32_t timeout_msec);


  • 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.

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