Hello Ma Shimiao,

A Debian user has applied to mention that strerror_r(3) is thread safe.

I quote his message [1]:

> Frome Martin Godisch <[email protected]>, Wed, 6 Apr 2011 09:30:30 +0200
> 
> Please add a note to vfprintf(3) telling users that the %m conversion
> specifier is thread safe.
>
> Rationale: errno(3) is thread local, strerror_r(3) is thread safe, and
> vfprintf(3) uses errno and strerror_r (in
> eglibc-2.11.2/stdio-common/vfprintf.c:974).

This is your area, it may interest you.
