I download tuxzap_programs-0.2.2 and  I see it also uses ostringstream
and no ostrstream.  However this time it's correct  because there is a
copy of the buffer _after_ it is initialized.
	
	char path[256];
	ostringstream str;
	
	[...] /* Initializing str */
	
	strcpy(path,str.str().data());
	
Note : I strongly recommand you to use strncpy() instead of strcpy(),
I would replace the last line with
	
	strncpy(path, str.str().data(), 256);
