Subject: [LTP] question about signal handling in tst_sig()
Date: Mon, 14 Mar 2016 16:19:07 +0800	[thread overview]
Message-ID: <20160314081907.GA3579@localhost.localdomain> (raw)

Hi there,

Looks like in tst_sig(), if _SC_SIGRT_MIN defined, all realtime signals
won't be set an handler:

125 #ifdef _SC_SIGRT_MIN
126                 if (sig >= sigrtmin && sig <= sigrtmax)
127                         continue;
128 #endif

but, if it wasn't defined, then all realtime signals will be set an
handler:

134 #if !defined(_SC_SIGRT_MIN) && defined(__SIGRTMIN) &&
defined(__SIGRTMAX)
135                         /* Ignore all real-time signals */
136                 case __SIGRTMIN:
137                 case __SIGRTMIN + 1:
...

is that correct, or I missed something here? 

Thanks in advance!
