you've made to the output format? You can just send a patch
for help.c.
Thanks,
Dave
With the help file (have a look to the english ...), i have done a small
modification in the output (BLOCKED is really generic).
SIGPENDING: no
BLOCKED: 8000000200000800
PRIVATE_PENDING
SIGNAL: 0000000200000800
SIGQUEUE: SIG SIGINFO
12 f51b9c84
34 f51b9594
SHARED_PENDING
SIGNAL: 8000000000000800
S IGQUEUE: SIG SIGINFO
