It's my bestst:

int split(char delem, char *str, ... )
{
char *tmp, *_src, *t, **s;
int fields = 0;

_src = str;

va_list ap;
va_start(ap, str);

if (! (tmp=new char[2048]) )
return -1;

while(_src)
{ t = _src;
while (*t && ((*t) != delem) ) ++t;
s = va_arg(ap, char **);
if (!s || !*t)
break;
*s = ( t-_src-1 > 0) ? strndup(_src,t-_src-1) : 0 ;
_src = t+1;
++ fields;
}

return fields;
}
