### Description
The platform independent function `httplib_pthread_setspecific()` is used to set a key value for a previously obtained thread specific key. The function returns **0** when successful and an error code if something went wrong. On systems which support it, the functionality is implemented as a direct call to `pthread_setspecific()`. Otherwise an OS dependent alternative function is called.
