zmq_has - Man Page

int zmq_has (const char *capability);

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.
