mongoc_stream_write()#

Synopsis#

ssize_t
mongoc_stream_write (mongoc_stream_t *stream,
                     void *buf,
                     size_t count,
                     int32_t timeout_msec);

Parameters#

stream: A mongoc_stream_t.
buf: The buffer to write.
count: The number of bytes to write.
timeout_msec: The number of milliseconds to wait before failure, a timeout of 0 will not block. If negative, use the default timeout.

The mongoc_stream_write() function shall perform a write to a mongoc_stream_t. It’s modeled on the API and semantics of write(), though the parameters map only loosely.

Returns#

The mongoc_stream_write() function returns the number of bytes written on success. It returns -1 and sets errno upon failure.
