* libc/stdlib/abort.c: changed description: uses "raise" instead of
"getpid" and "kill"; added: uses "write" and "_exit".
Also included unistd.h for "_exit" prototype.
* libc/stdlib/system.c: included unistd.h for "execve" prototype,
reent.h for "_fork_r" and "_wait_r" prototypes.
(do_system): changed extern char *environ[] to POSIX-friendly
extern char **environ.
* libc/stdlib/wctomb_r.c: included string.h for "strlen" and "strcmp"
prototypes.
* libc/stdlib/remove.c: included reent.h for "_unlink_r" prototype.
* libc/reent/execr.c: included sys/wait.h for "wait" prototype.
* libc/reent/fstatr.c: included sys/stat.h for "fstat" prototype.
* libc/reent/openr.c: included fcntl.h for "open" prototype.
* libc/reent/signalr.c: included signal.h for "kill" prototype,
unistd.h for "getpid" prototype.
* libc/reent/statr.c: included sys/stat.h for "stat" prototype.
* libc/reent/timer.c: included sys/time.h for "gettimeofday" prototype.
* libc/unix/getut.c (utmpname): removed local, incorrect "strdup"
prototype. Also included stdlib.h for "abort", string.h for
"strdup" and "strncmp" prototypes.
* libc/unix/getlogin.c: included string.h for "strncmp", "memset", and
"strncpy", unistd.h for "read" and "close" prototypes.
* libc/posix/execvp.c: included string.h for "strchr", "strlen", and
"strcat" prototypes.

FUNCTION
|
|
<<abort>>---abnormal termination of a program
|
|
|
|
INDEX
|
|
abort
|
|
|
|
ANSI_SYNOPSIS
|
|
#include <stdlib.h>
|
|
void abort(void);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdlib.h>
|
|
void abort();
|
|
|
|
DESCRIPTION
|
|
Use <<abort>> to signal that your program has detected a condition it
|
|
cannot deal with. Normally, <<abort>> ends your program's execution.
|
|
|
|
Before terminating your program, <<abort>> raises the exception <<SIGABRT>>
|
|
(using `<<raise(SIGABRT)>>'). If you have used <<signal>> to register
|
|
an exception handler for this condition, that handler has the
|
|
opportunity to retain control, thereby avoiding program termination.
|
|
|
|
In this implementation, <<abort>> does not perform any stream- or
|
|
file-related cleanup (the host environment may do so; if not, you can
|
|
arrange for your program to do its own cleanup with a <<SIGABRT>>
|
|
exception handler).
|
|
|
|
RETURNS
|
|
<<abort>> does not return to its caller.
|
|
|
|
PORTABILITY
|
|
ANSI C requires <<abort>>.
|
|
|
|
Supporting OS subroutines required: <<_exit>> and optionally, <<write>>.
