SYNOPSIS PARAMETERS RETURNS AUTHOR COPYRIGHT

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.
