0MQ 4.3.5                                          03/31/2024                                         ZMQ_HAS(3)

       The zmq_has() function shall report whether a specified capability is available in the library. This
       allows bindings and applications to probe a library directly, for transport and security options.

       Capabilities shall be lowercase strings. The following capabilities are defined:

       •   ipc - the library supports the ipc:// protocol

       •   pgm - the library supports the pgm:// protocol

       •   tipc - the library supports the tipc:// protocol

       •   norm - the library supports the norm:// protocol

       •   curve - the library supports the CURVE security mechanism

       •   gssapi - the library supports the GSSAPI security mechanism

       •   draft - the library is built with the draft api

       When this method is provided, the zmq.h header file will define ZMQ_HAS_CAPABILITIES.

       The zmq_has() function shall return 1 if the specified capability is provided. Otherwise it shall return
       0.
