- * Write a loose blob to the Object Database from a
- * provider of chunks of data.
- *
- * If the `hintpath` parameter is filled, it will be used to determine
- * what git filters should be applied to the object before it is written
- * to the object database.
- *
- * The implementation of the callback MUST respect the following rules:
- *
- *  - `content` must be filled by the callback. The maximum number of
- *    bytes that the buffer can accept per call is defined by the
- *    `max_length` parameter. Allocation and freeing of the buffer will
- *    be taken care of by libgit2.
- *
- *  - The `callback` must return the number of bytes that have been
- *    written to the `content` buffer.
- *
- *  - When there is no more data to stream, `callback` should return 0.
- *    This will prevent it from being invoked anymore.
- *
- *  - If an error occurs, the callback should return a negative value.
- *    This value will be returned to the caller.
- *
- * @param id Return the id of the written blob
- * @param repo Repository where the blob will be written.
- *        This repository can be bare or not.
- * @param hintpath If not NULL, will be used to select data filters
- *        to apply onto the content of the blob to be created.
- * @return 0 or error code (from either libgit2 or callback function)
