mciSendString playing sound overlapping?

[Anonymous]

I know how to use mciSendString to play a wav through.  However in games a wav file starts and the next one cuts it off short.  How do I overlap wave files?

my code here below for refference
-----8<--------cut here----------->8---------
#include <mmsystem.h>

VAR(soundvol, 0, 255, 255);
VAR(musicvol, 0, 128, 255);

#define MAXVOL 255

void cleansound() {};

void initsound() { };

void midi(char *name)
{
   int mcierr;
   if(soundvol && musicvol)
    {
        string sn;
        strcpy_s(sn, "open ");
        strcat_s(sn, name);
        strcat_s(sn, " type sequencer alias midi");
        mcierr = mciSendString("close all", "", 0, 0);
        midiOutSetVolume ( 0, 34592);
        if (mcierr)
           {
            conoutf("failed to close midi sequencer!");
            return;
            };
        mcierr = mciSendString(sn, 0, 0, 0);
        if (mcierr)
           {
            conoutf("failed to load midi music!");
            return;
            };
        mcierr = mciSendString("play midi", 0, 0, 0);
        if (mcierr)
           {
            conoutf("failed to play midi!");
            return;
            };
    };
};

COMMAND(midi, ARG_1STR);

cvector snames;

int registersound(char *name)
{
    loopv(snames) if(strcmp(snames[i], name)==0) return i;
    snames.add(newstring(name));
};

COMMAND(registersound, ARG_1EST);

void playsoundc(int n) { addmsg(0, 2, SV_SOUND, n); playsound(n); };

void playsound(int n, vec *loc)
{
  int mcierr;
    if(soundvol && musicvol)
    {
        string sn;
        strcpy_s(sn, "open sounds/");
        strcat_s(sn, snames[n]);
        strcat_s(sn, ".wav type waveaudio alias wav");
        waveOutSetVolume ( 0, 34952);
        mciSendString("close all", "", 0, 0);
        if (mcierr)
           {
            conoutf("failed to close sound!");
            return;
            };
        mcierr = mciSendString(sn, 0, 0, 0);
        if (mcierr)
           {
            conoutf(sn);
            return;
            };
        mcierr = mciSendString("play wav", 0, 0, 0);
        if (mcierr)
           {
            conoutf("failed to play sound!");
            return;
            };
    };
};

void sound(int n) { playsound(n, NULL); };
COMMAND(sound, ARG_1INT);

I have no idea.  Maybe someone else here has an answer?

Wow, I haven't seen ---8<---cut here--->8--- in a long time!  You must be older dirt.  I tried to sign up here but they make it a regular pain in the @ss to do it.... so I post as nobody.   I think this should solve your prob.
set volume as a DWORD and left and right int
---8<---cut here--->8---
void playsound(int n, vec *loc)
{
    if(!soundvol) return;
    if(lastmillis==lastsoundmillis) soundsatonce++; else soundsatonce = 1;
    lastsoundmillis = lastmillis;
    if(soundsatonce>5) return;
    string wid;
    if(soundvol && musicvol)
    {  
      switch (soundsatonce) //take a number have a seat
      {
      case 1: strcpy_s(wid, "dev01"); break;
      case 2: strcpy_s(wid, "dev02"); break;
      case 3: strcpy_s(wid, "dev03"); break;
      case 4: strcpy_s(wid, "dev04"); break;
      case 5: strcpy_s(wid, "dev05"); break;
       };
 
        //shut down free device        
        string sn;
        strcpy_s(sn, "close ");
        strcat_s(sn, wid);

Dang!! they don't make it easy to post here...

Whoa I haven't seen that in years!  You must be older than dirt cause so am I!!  Here is my answer to your prob...

Try PlaySound() with SND_ASYNC as its flag =)
