There are a huge list of functions in POSIX which are not
safe to use from multiple threads currently. I generated
the list by looking at all libc symbol exports for variants
which have a parallel _r symbol.
nm -D --defined-only /lib/libc.so.6 \
| grep '_r$' \
| awk '{print $3}' \
| grep -v __ \
| grep -v qsort \
| grep -v readdir \
| sort \
| uniq \
| sed -e 's/_r//'
Nice. ACK.
FYI, I get the identical list on x86_64 F10 with this:
nm -D --defined-only /lib64/libc.so.6 \
| perl -nle '/ ([^_]\w+)_r$/ and print $1'|grep -vE 'qsort|readdir'
