Description

mongoc_stream_readv - mongoc_stream_readv()

ssize_t
mongoc_stream_readv (mongoc_stream_t *stream,
mongoc_iovec_t *iov,
size_t iovcnt,
size_t min_bytes,
int32_t timeout_msec);

	•		stream: A mongoc_stream_t.
	•		iov: A vector of mongoc_iovec_t.
	•		iovcnt: The number of items in iov.
	•		min_bytes: The minimum number of bytes to read or failure will be indicated.
	•		timeout_msec: A timeout in milliseconds, or 0 to indicate non-blocking. A negative value with use the default timeout.

This function is identical to mongoc_stream_read() except that it takes a mongoc_iovec_t to perform gathered I/O.

>= 0 on success, -1 on failure and errno is set.
