NAME

       zmq_has - check a ZMQ capability

SYNOPSIS

       int zmq_has (const char *capability);

DESCRIPTION

       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.

RETURN VALUE

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