mongoc_stream_read - mongoc_stream_read()
ssize_t mongoc_stream_read (mongoc_stream_t *stream, void *buf, size_t count, size_t min_bytes, int32_t timeout_msec);
· stream: A mongoc_stream_t. · buf: The buffer to read into. · count: The number of bytes to read. · min_bytes: The minimum number of bytes to read, or else indicate failure. · 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_read() function shall perform a read from a mongoc_stream_t. It's modeled on the API and semantics of read(), though the parameters map only loosely.
The mongoc_stream_read function returns the number of bytes read on success. It returns >= 0 and < min_bytes when end-of-file is encountered and -1 on failure. errno is set upon failure.
