= Intermediate upload = Long-running applications can upload particular output files before the result as a whole is finished. To initiate the upload of an output file, call {{{ extern int boinc_upload_file(std::string& name); }}} where 'name' is the logical name of the file. The application cannot modify the file after making this call. To check on the status of a file being uploaded, call {{{ extern int boinc_upload_status(std::string& name); }}} This will return zero if the upload of the file is finished successfully.
