[Pharo-project] OpenSSL - a couple of questions

Hello all, Do you have any thoughts on whether a wrapper for OpenSSL should be a plugin or based on FFI/Alien? Would blocking calls be best handled by using OS threads or non-blocking sockets? In either case, I would envision using semaphores to block only the calling Process instance. Loosely related, can you understand (and explain to me - perhaps the hard part<g>) the following syntax: void (*CRYPTO_get_locking_callback(void))(int mode,int type,const char *file,int line); It looks to me like a shotgun wedding of an incomplete typedef of a function pointer type and a function prototype. Any ideas? Bill
