- * Read data from a file descriptor, and send it to the afs process.

- * \param scc crypt context containing the file descriptor to read data from.
- * \param arg_obj Pointer to the arguments to \a f.
- * \param f The callback function.
- * \param max_len Don't read more than that many bytes from stdin.
- * \param result_handler See \ref send_callback_request.
- * \param private_result_data See \ref send_callback_request.

- * This function is used by commands that wish to let para_server store
- * arbitrary data specified by the user (for instance the add_blob family of
- * commands). First, at most \a max_len bytes are read and decrypted from the
- * file descriptor given by \a scc. The result is concatenated with the buffer
- * given by \a arg_obj, and the combined buffer is made available to the afs
- * process via the callback method. See \ref send_callback_request for details.
