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.
