Default thread library
 

Not sure if this is the right forum to post this question...

When pthread_create() is called from user code, how can I find out which version of the implementation is used, LinuxThreads or NPTL?

If
doesn't print anything, can I assume LinuxThreads is used as the default thread library?

Thank,

that command gives a return on both.
like that so i guess you can just parse the output and determine the default.
for now at least most all linux systems use NPTL as default but also have linuxthreads as a fallback unless someone specifically compiles their glibc without linuxthreads or the system is very old and has linuxthreads only.
