sysdecode_sigcode —
lookup name of signal code
LIBRARY
System Argument Decoding Library (libsysdecode, -lsysdecode)
SYNOPSIS
#include
<sysdecode.h>
const char *
sysdecode_sigcode(int
signal, int
si_code);
DESCRIPTION
The
sysdecode_sigcode()
function returns a text description of the si_code
field of the siginfo_t object associated with an
instance of signal sig. The text description contains
the name of the C macro whose value matches si_code.
General purpose signal codes such as SI_USER are
handled as well as signal-specific codes for SIGBUS,
SIGCHLD, SIGFPE,
SIGILL, SIGSEGV and
SIGTRAP. If si_code does not
represent a known signal code, sysdecode_sigcode()
returns NULL.
RETURN VALUES
The sysdecode_sigcode() function returns a
pointer to a signal code description or NULL if
si_code is not a known signal code.
