Subject: manpages-dev: raise(int sig) is incorrectly described as sending signal to the calling process

Date: Thu, 17 Apr 2008 00:26:57 +0100

Package: manpages-dev
Version: 2.79-2
Severity: normal

The manpage for raise, incorrectly describes it as sending a signal to the current process;
infact it sends the signal to the calling thread. Therefore the statement that  raise(sig) is
equivalent to kill(getpid(), sig) is false.

Do you have a proof for this claim?

In terms of specified behaviour, I refer you to POSIX:
http://www.opengroup.org/onlinepubs/009695399/functions/raise.html

The Glibc manual is also in error.

In terms of actual behaviour, I have observed this behaviour whilst developing a
program which uses signals inter-thread communication. I am unable to supply a
test case at this moment due to a hardware failure on my Linux system.

I see.

Could you file a separate bug report against glibc-doc if you haven't
done so already.

Timothy is correct here -- I will fix the page.

Timothy -- thanks for your report.  I've added text to the upstream
2.80 release to clarify the details for multithreaded programs.

Cheers,
