ABORT2(2) BSD System Calls Manual ABORT2(2)NAME
abort2 -- abort process with diagnostics
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdlib.h>
void
abort2(const char *why, int nargs, void **args);
DESCRIPTION
The abort2() system call causes the process to be killed and the specified diagnostic message (with arguments) to be delivered by the kernel
to the syslogd(8) daemon.
The why argument points to a NUL-terminated string specifying a reason of the program's termination (maximum 128 characters long). The args
array contains pointers which will be logged numerically (with the kernel's '%p' printf(9) format). The nargs argument specifies the number
of pointers in args (maximum 16).
The abort2() system call is intended for use in situations where continuation of a process is impossible or for other definitive reasons is
unwanted, and normal diagnostic channels cannot be trusted to deliver the message.
RETURN VALUES
The abort2() function never returns.
The process is killed with SIGABRT unless the arguments to abort2() are invalid, in which case SIGKILL is used.
EXAMPLES
#include <stdlib.h>
if (weight_kg > max_load) {
void *ptrs[3];
ptrs[0] = (void *)(intptr_t)weight_kg;
ptrs[1] = (void *)(intptr_t)max_load;
ptrs[2] = haystack;
abort2("Camel overloaded", 3, ptrs);
}
SEE ALSO abort(3), exit(3)HISTORY
The abort2() system call first appeared in FreeBSD 7.0.
AUTHORS
The abort2() system call was designed by Poul-Henning Kamp <phk@FreeBSD.org>. It was implemented by Wojciech A. Koszek
<dunstan@freebsd.czest.pl>.

abort(3C) Standard C Library Functions abort(3C)NAME
abort - terminate the process abnormally
SYNOPSIS
#include <stdlib.h>
void abort(void);
DESCRIPTION
The abort() function causes abnormal process termination to occur, unless the signal SIGABRT is being caught and the signal handler does
not return. The abnormal termination processing includes at least the effect of fclose(3C) on all open streams and message catalogue
descriptors, and the default actions defined for SIGABRT. The SIGABRT signal is sent to the calling process as if by means of the raise(3C)
function with the argument SIGABRT.
The status made available to wait(3C) or waitpid(3C) by abort will be that of a process terminated by the SIGABRT signal. abort will
override blocking or ignoring the SIGABRT signal.
RETURN VALUES
The abort() function does not return.
ERRORS
No errors are defined.
USAGE
Catching the signal is intended to provide the application writer with a portable means to abort processing, free from possible interfer-
ence from any implementation-provided library functions. If SIGABRT is neither caught nor ignored, and the current directory is writable,
a core dump may be produced.
