/* Macro for defining "auto-load" functions.
* Note that this is self-modifying code *gasp*.
* The first invocation of a routine will trigger the loading of
* the DLL. This will then be followed by the discovery of
* the procedure's entry point, which is placed into the location
* pointed to by the stack pointer. This code then changes
* the "call" operand which invoked it to a "jmp" which will
* transfer directly to the DLL function on the next invocation.
*
* Subsequent calls to routines whose transfer address has not been
* determined will skip the "load the dll" step, starting at the
* "discovery of the entry point" step.
*
* So, immediately following the the call to one of the above routines
* we have:
* DLL info (4 bytes) Pointer to a block of information concerning
* the DLL (see below).
* DLL args (4 bytes) The number of arguments pushed on the stack by
* the call. If this is an odd value then this
* is a flag that non-existence of this function
* is not a fatal error
* func name (n bytes) asciz string containing the name of the function
* to be loaded.
*
* The DLL info block consists of the following
* load_state (4 bytes) Pointer to a word containing the routine used
* to eventually invoke the function. Initially
* points to an init function which loads the
* DLL, gets the process's load address,
* changes the contents here to point to the
* function address, and changes the call *(%eax)
* to a jmp func. If the initialization has been
* done, only the load part is done.
* DLL handle (4 bytes) The handle to use when loading the DLL.
* DLL locker (4 bytes) Word to use to avoid multi-thread access during
* initialization.
* extra init (4 bytes) Extra initialization function.
* DLL name (n bytes) asciz string containing the name of the DLL.
*/

additional initialization routine to call prior to calling the first
function. */

* autoload.cc: Load eight more functions for waveIn support. * fhandler.h (class fhandler_dev_dsp): Add class Audio, class Audio_in and class Audio_out members and audio_in_, audio_out_ pointers so that future changes are restricted to file fhandler_dsp.cc. * fhandler_dsp.cc (fhandler_dev_dsp::Audio): Add this class to treat things common to audio recording and playback. Add more format conversions. (fhandler_dev_dsp::Audio::queue): New queues for buffer management to fix incomplete cleanup of buffers passed to the wave device. (fhandler_dev_dsp::Audio_in): New, added class to implement audio recording. (fhandler_dev_dsp::Audio_out): Rework to use functionality provided by fhandler_dev_dsp::Audio. Allocate memory audio buffers late, just before write. (fhandler_dev_dsp::Audio_out::start): Size of wave buffer allocated here depends on audio rate/bits/channels. (fhandler_dev_dsp::Audio_in::start): Ditto. (fhandler_dev_dsp::setupwav): Replaced by following function. (fhandler_dev_dsp::Audio_out::parsewav): Does not setup wave device any more. Discard wave header properly. (fhandler_dev_dsp::open): Add O_RDONLY and_RDWR as legal modes. Protect against re-open. Activate fork_fixup. (fhandler_dev_dsp::ioctl): Protect against actions when audio is active. SNDCTL_DSP_GETFMTS only returns formats supported by mmsystem wave API, not all supported formats. SNDCTL_DSP_GETBLKSIZE result now depends on current audio format. (fhandler_dev_dsp::fixup_after_fork): Call fork_fixup for the Audio classes to let them duplicate the CRITICAL_SECTION.
