Hi Community!!!
The Signal range of Neutrino is:
1 … 57---------- 57 POSIX signals (including traditional UNIX signals)
41 … 56--------- 16 POSIX realtime signals (SIGRTMIN to SIGRTMAX)
57 … 64--------- Eight special-purpose QNX Neutrino signals
as far as good but I can’t find a chart of QNX4.
How can I find a Signal range of ONX4 ?
Thank you.

Thank you mario

it seems to be 32 are this the traditional UNIX signals???
Thank you !! 
Yes it’s pretty much the norm.
