NAME
----
zsys - system wrapper

SYNOPSIS
--------
----
//  Callback for interrupt signal handler
typedef void (zsys_handler_fn) (int signal_value);

//  Set interrupt handler (NULL means external handler)
CZMQ_EXPORT void
    zsys_handler_set (zsys_handler_fn *handler_fn);

//  Reset interrupt handler, call this at exit if needed
CZMQ_EXPORT void
    zsys_handler_reset (void);

//  Self test of this class
CZMQ_EXPORT int
    zsys_test (bool verbose);
----

DESCRIPTION
-----------

The zsys class provides a portable wrapper for miscellaneous functions
that we want to wrap but which don't fit into any of the existing
classes. Eventually all non-portable functionality might be moved here
but for now it covers only file systems.


EXAMPLE
-------
.From zsys_test method
