- since the new version of the pthread_cond_wait()
function has performance degradation in multi-core
scenarios, here is an extra libpthreadcond.so using
old version of the function. you can use it by adding
LD_PRELOAD=./libpthreadcond.so in front of your program
(eg: LD_PRELOAD=./libpthreadcond.so ./test).
use with-libpthreadcond to compile it.
warning:2.17 version pthread_cond_wait() does not meet
the posix standard, you should pay attention when using
it.
