You could try system("/bin/cat <file>.wav > /dev/dsp"). Note that this 
does not handle mp3's just wav's.

(Note that /bin/cat will probably not work for a Turbo C program because 
/bin/cat is a Posix path. You might need to do something more like 
system("C:\Cygwin\bin\bash -c '/bin/cat <file>.wav > /dev/dsp'"). Also 
note that you need to subsititute a real wav file name for <file>.wav).

Ah, but there is a "dir.exe" in fileutils on Cygwin.  IOW, the following
worked for me:

$ cat > moises.c
#include <stdlib.h>
main() {
  system("dir");
}
$ make moises
gcc     moises.c   -o moises
$ ./moises
moises.c  moises.exe
$

At a guess, the OP is not using gcc or Cygwin at all.  If so, the question
is off-topic for this list.

This program will not work. There is no program called 'dir' in Windows. You
probably want something like 'cmd /c dir'.

It did not work. Will it be that I found a bug??? How much luck I have.. :-) 
It follows the source. that program does not do anything of important! It is 
alone a test. 

what we most can do? 

I changed the command for "DIR" who list the directories of the windows just 
to facilitate the comprehension and so that it to do not are necessary to do 
an upload of sound.exe. Try, with that program execute some other command! 
Here, already tried of everything, and anything (not) worked.

Ok.  The next question is if "sound.exe" is in your path.  Does something
like:

system("/cygdrive/c/dir/sound.exe")

work?

/cygdrive/c/dir would be cygwin's way of typing c:/dir

dir would be the place where sound.exe lives.

Yes. 

When entering with the command ls -l /bin/sh.exe, the appeared following: 

-rwxr-x---+ 1 Diego  Usuários  83456 Aug 11 10:45 /bin/sh.exe 


And now? what Do I do? Does that mean something? How I said, or the command 
system() works, or I learn to activate speaker through cygwin. In ultimo 
case, whether someone knows how to execute a .WAV or .MP3 and can explain am 
thankful. 

The important is that my program of a sonorous warning when I need. 

Thanks. 

As usual, apologizing me for bad English.

Do you have the file /bin/sh.exe on your system?

ls -l /bin/sh.exe

would tell you.

system() refuses to work!!! HELP

[Moises D. Deangelo]

Hi Personal. 

Please, my program keep working for several and several hours. 
I want when he finish, which he warns me. To do not complicate my work wish 
to activate speaker, but I do not have been having success. 

I use platform w2k, and clear, cygwin. 

As I do not manage to activate speaker by cygwin, tried by the Turbo C. 

But my program is done in cygwin, and it does not run in TC. I tried to 
place in the source of my program 
system(sound.exe). 

Sound.exe is developed in TC and would be the program that activates 
speaker. 

This way, when my program finished, he would call that other program 
sound.exe that then it would activate speaker. 

But system() refuses to work. 

Summarizing. Or I activate speaker using cygwin, or I manage to do cygwin 
call a program that can activate. 

Can anybody help? 

Apologize me for my badly English. 

Moises Deangelo 
Brazil.
