            Bug ID: 29812
           Summary: Tunables for libstdc++
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: jwakely.gcc at gmail dot com
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

There are several things I'd like to use tunables for in libstdc++:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D88264

But there's no thread-safe way to do that if libstdc++.so can be dlopened.

Would it be possible for glibc to reserve some tunables under the glibcxx.*
namespace and provide a safe way for libstdc++ to get read-only access to
those?
