As libzmq is compiled with optional transports and security mechanisms, there is no clean way for applications to determine what capabilities are actually available in a given libzmq instance. Solution: provide an API specifically for capability reporting. The zmq_has () method is meant to be open ended. It accepts a string so that we can add arbitrary capabilities without breaking existing applications. zmq.h also defines ZMQ_HAS_CAPABILITIES when this method is provided.

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
|
|
|
|
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.
