Description
The platform independent function httplib_pthread_key_create() creates a key to a memory area for thread specific data storage. 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_key_create(). Otherwise own code is used to emulate the same behaviour.
Please not that on systems which don't support the pthread_key_create() function natively that the destructor parameter is ignored. For multiplatform execution you should check that this will not cause problems regarding the functionality.
