hi kjetil,

I'm working on the snd external, and wonder about gensyms thread safety. It looks to be, but I'm not quite sure. In case it isn't is there a locking-mechanism or something I can use?

I also see that there are some functions called sys_lock or something, how does they work?

gensym is basically not thread safe ... for the devel branch i made gensym threadsafe, but if you want to write code for miller's pd, you need to use the syslock ...

Thanks! So how do I use syslock from another thread?

Does this make sence:?

t_symbol *thread_safe_gensym(char *symbol){ t_symbol *ret; sys_lock(); ret=gensym(symbol); sys_unlock(); return ret; }
