NAME
     os_log_create -- create an object that tracks the state of logging for a
     given system.

SYNOPSIS
     #include <os/log.h>

     os_log_t
     os_log_create(const char *subsystem, const char *category);

DESCRIPTION
     Use os_log_create to create an object that can be passed to os_log(3)
     calls.  Log messages to this object will be marked with the object's sub-
     system and category name.  The behavior of log messages to this object
     can be configured using the log(1) command.

EXAMPLES
     Create a new os_log_t object and log a message:

           #include <os/log.h>

           /* create a log object for the subsystem, specifically the "connections" category" */
           os_log_t log = os_log_create("com.example.widget", "connections");

           /* log a connection related message */
           os_log(log, "connection state changed: %d interface: %s", if, interface);
