mongoc_stream_writev3
Usage
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 iniov.
- •
-
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.
Returns
The number of bytes written on success, or -1 upon failure and errno is set.
