ABORT2(2)		       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 continua-
     tion of a process is impossible or for  other  definitive	reasons  is  un-
     wanted,  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 in-
     valid, 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.

     The   abort2()   system   call   was   designed   by   Poul-Henning    Kamp

     stan@freebsd.czest.pl>.
