1. Pokud nepouzijete verzi s _p_ (execlp), musi "program" byt 
vcetne cesty (s p to hleda v PATH).
2. Posledni z parametru musi byt NULL, at vi, ze uz dalsi nejsou 
(jak jinak terminujete tri tecky, ze?)
3. Opravdu chcete verzsi s _e_ (v te predavate i environment)?


Takze asi chcete
execlp("program","program","param1","param2","param3",NULL);

man execlp
execlp na linux.cz
:-)
