@ -255,12 +255,14 @@ This value results in the kernel sending a
signal to the triggering process without executing the system call.
Various fields will be set in the
.I siginfo_t
structure associated with signal:
.IR siginfo\->si_call_addr
structure (see
.BR sigaction (2))
associated with signal:
.IR si_call_addr
will show the address of the system call instruction, and
.IR siginfo\->si_syscall
.IR si_syscall
and
.IR siginfo\->si_arch
.IR si_arch
will indicate which system call was attempted.
The program counter will be as though the system call happened
(i.e., it will not point to the system call instruction).
