Subject: Update: Ensure all programs are handling signals, adding signal_received to fll_progr... 
X-Git-Tag: 0.5.9~13
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=928bb81378ba50f086af5eb54327819751a523aa;p=fll

Update: Ensure all programs are handling signals, adding signal_received to fll_program_data_t.

Make sure fll_program_data_t supports storing the signal.
Move the commonly written functions that are pretty much identical across programs into fll_program:
- fll_program_standard_signal_received()
- fll_program_standard_signal_state()

Increase standard signal check from 10000 to 20000.
I really dislike the signal_check logic that exists purely as a work-around to the signal handling.
Most likely the only way to do this nicely that is available without rewritting the kernel and the libc will be to implement threads.
This will not be done for the 0.6.x versions and will likely happen for the 0.8.x versions.
