       mongoc_gridfs_file_writev - mongoc_gridfs_file_writev()

SYNOPSIS

          ssize_t
          mongoc_gridfs_file_writev (mongoc_gridfs_file_t *file,
                                     const mongoc_iovec_t *iov,
                                     size_t iovcnt,
                                     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.

       • timeout_msec: Unused.

DESCRIPTION

       Performs a gathered write to the underlying gridfs file.

       Modifying  GridFS files is NOT thread-safe. Only one thread or process can access a GridFS
       file while it is being modified.

RETURNS

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