[lvm-devel] [PATCH 5/8] Add tag_list_copy() supporting function inside lvm2app.

[Dave Wysochanski]

Add a supporting function to copy a list of internal tags to lvm2app list.
We need to put this here because of the lvm_str_list_t type which we export
in lvm2app.h.  If we didn't export this type, we could put this in the
internal library and use struct str_list.
