glibc as a shared object vs. strtok

["Stanisław T. Findeisen"]

Hello

I am having a question regarding strtok:

         #include <string.h>

         char *strtok(char *str, const char *delim);

The manual page says it is not thread safe because it uses a static 
buffer. The question is: how come this function can be a part of a 
shared object, and thus be shared among multiple processes?

Thanks!
