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.
