Subject: Progress: Continue program related work, updating fss_write.
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=8a76ddf401439dffe58062cedccd2199909bfd18;p=fll

Progress: Continue program related work, updating fss_write.

The work continues, focusing on preparing fss_write for handling all currently written fss_*_write programs.
This should also pave the way for supporting other fss-???? standards than are currently directly represented.

The individual write programs will be linked to the same library fss_write is.
These individual write programs will act as if they were passed the "--as XXXX".
For example, fss_basic_list would operate the same as "fss_write -a fss-0002".

Some of the programs may have vastly different functionality than others.
In any case that code can be shared that code will be shared.
