| TRACE_SIGNAL_DELIVER(9) | SIGNAL | TRACE_SIGNAL_DELIVER(9) |
NAME¶
trace_signal_deliver - called when a signal is delivered
SYNOPSIS¶
void trace_signal_deliver(int sig, struct siginfo * info, struct k_sigaction * ka);
ARGUMENTS¶
sig
signal number
info
pointer to struct siginfo
ka
pointer to struct k_sigaction
DESCRIPTION¶
A 'sig' signal is delivered to current process with 'info' siginfo, and it will be handled by 'ka'. ka->sa.sa_handler can be SIG_IGN or SIG_DFL. Note that some signals reported by signal_generate tracepoint can be lost, ignored or modified (by debugger) before hitting this tracepoint. This means, this can show which signals are actually delivered, but matching generated signals and delivered signals may not be correct.
