Re: threads package for libc6

[JonesMB <jonesmb@ziplink.net>]

I have another Linux threads question.  Since POSIX threads are already built 
into the libc6 in hamm, I assume that the standard C libraries are also 
thread-safe.  The guys who are developing on the Linux Debian systems that I 
built for them have been telling me of some odd things that they have 
observed.  Code with threads and select/read/write behaves differently on 
Linux than it does on Solaris.  They keep getting "resource not available" 
errors on the file descriptors.  On the Solaris man pages there is an 
MT-LEVEL section that specifies whether a function is thread safe or not.  
They assume that because a similar section is not seen in the Linux man 
pages, the functions may not be thread safe.  However I think that if libc6 
in hamm supports POSIX threads, then the library functions in there must be 
thread safe.  Any ideas on this from you guys?
