/* 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.
