Thanks, it works fine.
Now i need to get the full pathname of a file.

I call for that cyg_hal_sys_getcwd() declared in <cyg/hal/hal_io.h>: 
  externC char * cyg_hal_sys_getcwd(char * buf, size_t size);

I have a problem at link-edit. 
The symbol is unresolved.
It is not found in libtarget.a either.

Thanks,
Dominique
