Denys Vlasenko 3d5ed41252 Make strace_fopen abort on error 
Error from strace_fopen in main results in call to exit(1).
Error from strace_fopen in newoutf is propagated to newoutf
callers: startup_attach (where it results in exit(1))
and alloc_tcb (where error is ignored). In second case,
the behavior doesn't seem to be right: it means with -ff
on open error for new LOGFILE.PID the output will continue
to go into *the same file as the previous process* - which
would be confusing. Moreover, on droptcb outf may be closed
and the output of other, still running process outputting
to the same outf will be lost. I don't think this is sane.
IOW: in all cases, error in strace_fopen should be fatal.

* strace.c (strace_fopen): Abort on error instead of returning NULL.
  (newoutf): Change return type to void.
  (startup_attach): Remove error check on newoutf return value.
  (main): Remove error check on strace_fopen return value.

README 

This is strace 4.0, a system call tracer for SunOS 4.x, Linux, System
V release 4, Solaris 2.x and Irix 5.x.  strace is released under a
Berkeley-style license at the request of Paul Kranenburg; see the file
COPYRIGHT for details.

Read the INSTALL file for generic instructions on how to install
strace.  If configure cannot guess your system configuration, you can
specify it on the command line after the other options like this:

	./configure --prefix=/usr i486-linux

A single sunos4.1 binary should work on all the sun4, sun4c and sun4m
kernel architectures.  Let me know if sun4d doesn't work.  Other
i486-*-sysv4 systems may work with little or no tweaking.

See the file NEWS for information on what has changed in recent
versions.

See the file PORTING if you like strace but it doesn't work on an
operating system you use frequently.

See the file CREDITS to see who has contributed to strace.

See the file TODO if you feel like helping out.

You can get the latest version of strace from its homepage at
http://sourceforge.net/projects/strace/ .

Please send bug reports and enhancements to the strace
mailinglist at strace-devel@lists.sourceforge.net, or directly to
Wichert Akkerman <wakkerma@debian.org>
