NAME
zsock - Class for high-level socket API that hides libzmq contexts and sockets
SYNOPSIS
// This is a stable class, and may not change except for emergencies. It
// is provided in stable builds.
// This class has draft methods, which may change over time. They are not
// in stable releases, by default. Use --enable-drafts to enable.
// Create a new socket. Returns the new socket, or NULL if the new socket
// could not be created. Note that the symbol zsock_new (and other
// constructors/destructors for zsock) are redirected to the *_checked
// variant, enabling intelligent socket leak detection. This can have
// performance implications if you use a LOT of sockets. To turn off this
// redirection behaviour, define ZSOCK_NOCHECK.
CZMQ_EXPORT zsock_t *

CZMQ_EXPORT void
zsock_destroy (zsock_t **self_p);
// Bind a socket to a formatted endpoint. For tcp:// endpoints, supports
// ephemeral ports, if you specify the port number as "*". By default
// zsock uses the IANA designated range from C000 (49152) to FFFF (65535).
// To override this range, follow the "*" with "[first-last]". Either or
// both first and last may be empty. To bind to a random port within the
// range, use "!" in place of "*".
//
// Examples:
// tcp://127.0.0.1:* bind to first free port from C000 up
// tcp://127.0.0.1:! bind to random port from C000 to FFFF
// tcp://127.0.0.1:*[60000-] bind to first free port from 60000 up
// tcp://127.0.0.1:![-60000] bind to random port from C000 to 60000
// tcp://127.0.0.1:![55000-55999]
// bind to random port from 55000 to 55999
//
// On success, returns the actual port number used, for tcp:// endpoints,
// and 0 for other transports. On failure, returns -1. Note that when using
// ephemeral ports, a port may be reused by different services without
// clients being aware. Protocols that run on ephemeral ports should take
// this into account.

DESCRIPTION
The zsock class wraps the libzmq socket handle (a void *) with a proper structure that
follows the CLASS rules for construction and destruction. Some zsock methods take a void *
"polymorphic" reference, which can be either a zsock_t or a zactor_t reference, or a
libzmq void *.
Please add @discuss section in ./../src/zsock.c.
