ssize_t
mongoc_stream_read (mongoc_stream_t *stream,
void *buf,
size_t count,
size_t min_bytes,
int32_t timeout_msec);
PARAMETERS
- 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(3) function shall perform a read from a mongoc_stream_t \&. It's modeled on the API and semantics of read(3) , though the parameters map only loosely.
RETURNS
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.
