.SH "NAME"
zsock \- high\-level socket API that hides libzmq contexts and sockets
.SH "SYNOPSIS"
.sp
.nf
// 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 *
zsock_new (int type);
// Create a PUB socket\&. Default action is bind\&.
CZMQ_EXPORT zsock_t *
zsock_new_pub (const char *endpoint);

// Create a DEALER socket\&. Default action is connect\&.
CZMQ_EXPORT zsock_t *

// Create a ROUTER socket\&. Default action is bind\&.
CZMQ_EXPORT zsock_t *
zsock_new_router (const char *endpoint);
// Create a PUSH socket\&. Default action is connect\&.
CZMQ_EXPORT zsock_t *

// zsock_new method\&.
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\&.

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 *\&.
