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 >= 0 and < min_bytes when end-of-file is encountered and -1 on failure. errno is set upon failure.
