From: Kevin Day Date: Wed, 9 Sep 2020 04:09:06 +0000 (-0500) Subject: Progress: featureless make. X-Git-Tag: 0.5.0~12 X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=38eaac9290127863014a55a562ce2f1ff2f58ac8;p=fll Progress: featureless make. Implement file move functions. - There will need to be future changes to allow for moving across filesystems. - This move across filesystems may need to be an fll_file_move() so that it can either do a directory clone or a file clone. Fix a typo 'perforrm', which should instead be 'perform'. Add 'F_mount' status code. Implement the move section operation. --- diff --git a/level_0/f_directory/c/directory.h b/level_0/f_directory/c/directory.h index 19f998a..d22f6bb 100644 --- a/level_0/f_directory/c/directory.h +++
