+/* CHANGELOG FOR PORTMIDI
+ *     (see ../CHANGELOG.txt)
+ *
+ * NOTES ON HOST ERROR REPORTING: 
+ *
+ *    PortMidi errors (of type PmError) are generic, system-independent errors.
+ *    When an error does not map to one of the more specific PmErrors, the
+ *    catch-all code pmHostError is returned. This means that PortMidi has
+ *    retained a more specific system-dependent error code. The caller can
+ *    get more information by calling Pm_HasHostError() to test if there is
+ *    a pending host error, and Pm_GetHostErrorText() to get a text string
+ *    describing the error. Host errors are reported on a per-device basis 
+ *    because only after you open a device does PortMidi have a place to 
+ *    record the host error code. I.e. only 
+ *    those routines that receive a (PortMidiStream *) argument check and 
+ *    report errors. One exception to this is that Pm_OpenInput() and 
+ *    Pm_OpenOutput() can report errors even though when an error occurs,
+ *    there is no PortMidiStream* to hold the error. Fortunately, both
+ *    of these functions return any error immediately, so we do not really
+ *    need per-device error memory. Instead, any host error code is stored
+ *    in a global, pmHostError is returned, and the user can call 
+ *    Pm_GetHostErrorText() to get the error message (and the invalid stream
+ *    parameter will be ignored.) The functions 
+ *    pm_init and pm_term do not fail or raise
+ *    errors. The job of pm_init is to locate all available devices so that
+ *    the caller can get information via PmDeviceInfo(). If an error occurs,
+ *    the device is simply not listed as available.
+ *
+ *    Host errors come in two flavors:
+ *      a) host error 
+ *      b) host error during callback
+ *    These can occur w/midi input or output devices. (b) can only happen 
+ *    asynchronously (during callback routines), whereas (a) only occurs while
+ *    synchronously running PortMidi and any resulting system dependent calls.
+ *    Both (a) and (b) are reported by the next read or write call. You can
+ *    also query for asynchronous errors (b) at any time by calling
+ *    Pm_HasHostError().
+ *
+ * NOTES ON COMPILE-TIME SWITCHES
+ *
+ *    DEBUG assumes stdio and a console. Use this if you want automatic, simple
+ *        error reporting, e.g. for prototyping. If you are using MFC or some 
+ *        other graphical interface with no console, DEBUG probably should be
+ *        undefined.
+ *    PM_CHECK_ERRORS more-or-less takes over error checking for return values,
+ *        stopping your program and printing error messages when an error
+ *        occurs. This also uses stdio for console text I/O.
