How can I make my dissector handle multiple ports?

Question

My Dissector will use multiple ports across our network. How can I define them?

packet-bppcp.c dissector_add_uint("tcp.port", BPPCP_PORT, bppcp_handle);

packet-bppcp.h #define BPPCP_PORT 26810 /* 4006 4181 4192 45634 7003 9010 9020 */

See the HTTP dissector for an example:

#define TCP_DEFAULT_RANGE "80,3128,3132,5985,8080,8088,11371,1900,2869,2710"
[...]
range_convert_str(&global_http_tcp_range, TCP_DEFAULT_RANGE, 65535);
http_tcp_range = range_empty();
prefs_register_range_preference(http_module, "tcp.port", "TCP Ports",
                "TCP Ports range",
                &global_http_tcp_range, 65535);
