This fixes bug before where - it assigned same string buffer on stack to all devices. -- pm_macosx_term(), deleteDeviceName(): - devices strings allocated during pm_macosx_init() are deallocated. - -+ pm_macosx_init(), newDeviceName(): - registering kMIDIPropertyManufacturer + kMIDIPropertyModel + - kMIDIPropertyName for name strings instead of just name. - -/ pm_macosx_init(): - unsigned i to quiet compiler griping -- get_timestamp(): - no change right here but type of Pt_Time() was altered in porttime.h - so it matches type PmTimeProcPtr in assignment in this function. -/ midi_write(): - changed unsigned to signed to stop compiler griping - -portmidi.h ----------- -- Added void arg to Pm_GetHostError() to stop compiler gripe. - -pmtest.c ---------- -- Added Initialize and Terminate calls so that it doesn't - fail the 2nd time the test is run. - ------ - -PortMIDI changes of 11 Nov 2003 by X. J. Scott - -pmmacosx.c ----------- -- Handles ports that don't have the full set of property strings. - This fixes bug where crash would occur if a virtual port was present. - diff --git a/desiredata/portmidi_osx/porttime.h b/desiredata/portmidi_osx/porttime.h deleted file mode 100644 index fb57fe7d..00000000 --- a/desiredata/portmidi_osx/porttime.h +++ /dev/null @@ -1,33 +0,0 @@ -/* porttime.h -- portable interface to millisecond timer - * - * 27Jun02 XJS - altered type of Pt_Time() (in porttime.h & portmidi.c) so it matches PmTimeProcPtr - */ - -/* Should there be a way to choose the source of time here? */ - -#ifdef __cplusplus -extern "C" { -#endif - - -typedef enum { - ptNoError = 0, - ptHostError = -10000, - ptAlreadyStarted, - ptAlreadyStopped -} PtError; - - -typedef long PtTimestamp; - -typedef int (PtCallback)( PtTimestamp timestamp, void *userData ); - - -PtError Pt_Start(int resolution, PtCallback *callback, void *userData); -PtError Pt_Stop(void); // xjs, added void -int Pt_Started(void); // xjs, added void -PtTimestamp Pt_Time(void *time_info); /* xjs - added void *time_info so this f() is a PmTimeProcPtr, defined in portmidi.h */ - -#ifdef __cplusplus -} -#endif diff --git a/desiredata/portmidi_osx/ptdarwin.c b/desiredata/portmidi_osx/ptdarwin.c deleted file mode 100644 index de71d03b..00000000 --- a/desiredata/portmidi_osx/ptdarwin.c +++ /dev/null @@ -1,58 +0,0 @@ -/* - * Portable timer implementation for Darwin / MacOS X - * - * Jon Parise <jparise@cmu.edu> - * - * $Id: ptdarwin.c,v 1.9.2.2 2005-07-12 15:53:50 timblech Exp $ - */ - -#include <stdio.h> -#include <sys/time.h> -#include "porttime.h" - -#define TRUE 1 -#define FALSE 0 - -static int time_started_flag = FALSE; -static struct timeval time_offset; - -PtError Pt_Start(int resolution, PtCallback *callback, void *userData) -{ - struct timezone tz; - - if (callback) printf("error in porttime: callbacks not implemented\n"); - time_started_flag = TRUE; - gettimeofday(&time_offset, &tz); - - return ptNoError; -} - - -PtError Pt_Stop(void) // xjs added void -{ - time_started_flag = FALSE; - return ptNoError; -} - - -int Pt_Started(void) // xjs added void -{ - return time_started_flag; -} - - -PtTimestamp Pt_Time(void *time_info) // xjs added void *time_info -{ - long seconds, milliseconds; - struct timeval now; - struct timezone tz; - - gettimeofday(&now, &tz); - seconds = now.tv_sec - time_offset.tv_sec; - milliseconds = (now.tv_usec - time_offset.tv_usec) / 1000; - - return (seconds * 1000 + milliseconds); -} - - - |
