mongoc_stream_writev()¶
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 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.
Returns¶
The number of bytes written on success, or -1 upon failure and errno is set.
