  • file: A mongoc_gridfs_file_t.
  • iov: An array of mongoc_iovec_t.
  • iovcnt: The number of elements in iov.
  • timeout_msec: Unused.

Performs a gathered write to the underlying gridfs file.

The timeout_msec parameter is unused.

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

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