// This is a draft class, and may change without notice\&. It is disabled in
// stable builds by default\&. If you use this in applications, please ask
// for it to be pushed to stable state\&. Use \-\-enable\-drafts to enable\&.
#ifdef CZMQ_BUILD_DRAFT_API
// *** Draft method, for development use, may change without warning ***
// Returns CZMQ version as a single 6\-digit integer encoding the major
// version (x 10000), the minor version (x 100) and the patch\&.
CZMQ_EXPORT int
zproc_czmq_version (void);
// *** Draft method, for development use, may change without warning ***
// Returns true if the process received a SIGINT or SIGTERM signal\&.
// It is good practice to use this method to exit any infinite loop
// processing messages\&.
CZMQ_EXPORT bool
zproc_interrupted (void);
// *** Draft method, for development use, may change without warning ***
// Returns true if the underlying libzmq supports CURVE security\&.
CZMQ_EXPORT bool
zproc_has_curve (void);
// *** Draft method, for development use, may change without warning ***
// Return current host name, for use in public tcp:// endpoints\&.
// If the host name is not resolvable, returns NULL\&.
// Caller owns return value and must destroy it when done\&.
CZMQ_EXPORT char *
zproc_hostname (void);
// *** Draft method, for development use, may change without warning ***
// Move the current process into the background\&. The precise effect
// depends on the operating system\&. On POSIX boxes, moves to a specified
// working directory (if specified), closes all file handles, reopens
// stdin, stdout, and stderr to the null device, and sets the process to
// ignore SIGHUP\&. On Windows, does nothing\&. Returns 0 if OK, \-1 if there
// was an error\&.
CZMQ_EXPORT void
zproc_daemonize (const char *workdir);
// *** Draft method, for development use, may change without warning ***
// Drop the process ID into the lockfile, with exclusive lock, and
// switch the process to the specified group and/or user\&. Any of the
// arguments may be null, indicating a no\-op\&. Returns 0 on success,
// \-1 on failure\&. Note if you combine this with zsys_daemonize, run
// after, not before that method, or the lockfile will hold the wrong
// process ID\&.
CZMQ_EXPORT void
zproc_run_as (const char *lockfile, const char *group, const char *user);
// *** Draft method, for development use, may change without warning ***
// Configure the number of I/O threads that ZeroMQ will use\&. A good
// rule of thumb is one thread per gigabit of traffic in or out\&. The
// default is 1, sufficient for most applications\&. If the environment
// variable ZSYS_IO_THREADS is defined, that provides the default\&.
// Note that this method is valid only before any socket is created\&.
CZMQ_EXPORT void
zproc_set_io_threads (size_t io_threads);
// *** Draft method, for development use, may change without warning ***
// Configure the number of sockets that ZeroMQ will allow\&. The default
// is 1024\&. The actual limit depends on the system, and you can query it
// by using zsys_socket_limit ()\&. A value of zero means "maximum"\&.
// Note that this method is valid only before any socket is created\&.
CZMQ_EXPORT void
zproc_set_max_sockets (size_t max_sockets);
// *** Draft method, for development use, may change without warning ***
// Set network interface name to use for broadcasts, particularly zbeacon\&.
// This lets the interface be configured for test environments where required\&.
// For example, on Mac OS X, zbeacon cannot bind to 255\&.255\&.255\&.255 which is
// the default when there is no specified interface\&. If the environment
// variable ZSYS_INTERFACE is set, use that as the default interface name\&.
// Setting the interface to "*" means "use all available interfaces"\&.
CZMQ_EXPORT void
zproc_set_biface (const char *value);

// *** Draft method, for development use, may change without warning ***
// Set log identity, which is a string that prefixes all log messages sent
// by this process\&. The log identity defaults to the environment variable
// ZSYS_LOGIDENT, if that is set\&.
CZMQ_EXPORT void
zproc_set_log_ident (const char *value);
// *** Draft method, for development use, may change without warning ***
// Sends log output to a PUB socket bound to the specified endpoint\&. To
// collect such log output, create a SUB socket, subscribe to the traffic
// you care about, and connect to the endpoint\&. Log traffic is sent as a
// single string frame, in the same format as when sent to stdout\&. The
// log system supports a single sender; multiple calls to this method will
// bind the same sender to multiple endpoints\&. To disable the sender, call
// this method with a null argument\&.
CZMQ_EXPORT void
zproc_set_log_sender (const char *endpoint);
// *** Draft method, for development use, may change without warning ***
// Enable or disable logging to the system facility (syslog on POSIX boxes,
// event log on Windows)\&. By default this is disabled\&.
