NAME

       mongoc_stream_read - mongoc_stream_read()

SYNOPSIS

          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() 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.

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.
