10 // This is a stable class, and may not change except for emergencies. It

13 // in stable releases, by default. Use --enable-drafts to enable.
14 // Create a new socket. Returns the new socket, or NULL if the new socket
15 // could not be created. Note that the symbol zsock_new (and other
16 // constructors/destructors for zsock) are redirected to the *_checked
17 // variant, enabling intelligent socket leak detection. This can have
18 // performance implications if you use a LOT of sockets. To turn off this
19 // redirection behaviour, define ZSOCK_NOCHECK.

80 // To override this range, follow the "*" with "[first-last]". Either or
81 // both first and last may be empty. To bind to a random port within the
82 // range, use "!" in place of "*".

84 // Examples:
85 // tcp://127.0.0.1:* bind to first free port from C000 up
86 // tcp://127.0.0.1:! bind to random port from C000 to FFFF
87 // tcp://127.0.0.1:*[60000-] bind to first free port from 60000 up

95 // clients being aware. Protocols that run on ephemeral ports should take

1321 The zsock class wraps the libzmq socket handle (a void *) with a proper
1322 structure that follows the CLASS rules for construction and
1323 destruction. Some zsock methods take a void * "polymorphic" reference,
1324 which can be either a zsock_t or a zactor_t reference, or a libzmq void
1325 *.
