SYNOPSIS
          ssize_t
          mongoc_gridfs_file_readv (mongoc_gridfs_file_t *file,
                                    mongoc_iovec_t *iov,
                                    size_t iovcnt,
                                    size_t min_bytes,
                                    uint32_t timeout_msec);


PARAMETERS
       • file: A mongoc_gridfs_file_t.

       • iov: An array of mongoc_iovec_t.

       • iovcnt: The number of elements in iov.

       • min_bytes: The minimum number of bytes that must be read or an error will be synthesized.

       • timeout_msec: Unused.


DESCRIPTION
       This function performs a scattered read from file, potentially blocking to read from the MongoDB server.

       The timeout_msec parameter is unused.


RETURNS
       Returns  the  number  of  bytes  read, or -1 on failure. Use mongoc_gridfs_file_error() to retrieve error
       details.
