mongoc_stream_readv - Man Page

Synopsis

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

Parameters

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

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

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