mongoc_stream_writev man page

mongoc_stream_writev() — 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.

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(3) function shall perform a write to a mongoc_stream_t writev(3) , though the parameters map only loosely.
