int nng_pipe_getopt_bool(nng_pipe p, const char *opt, bool *bvalp);
int nng_pipe_getopt_int(nng_pipe p, const char *opt, int *ivalp);
int nng_pipe_getopt_ms(nng_pipe p, const char *opt, nng_duration *durp);
int nng_pipe_getopt_ptr(nng_pipe p, const char *opt, void **ptr);
int nng_pipe_getopt_sockaddr(nng_pipe p, const char *opt, nng_sockaddr *sap);
int nng_pipe_getopt_string(nng_pipe p, const char *opt, char **strp);
