As I understand it, the "const char *" means that fopen() cannot modify the pointer in any way. It's perfectly OK to pass it any character pointer. The pointer doesn't have to be a string constant. Such a prototype isn't really necessary; most likely it is there to reassure you, the programmer, that the pointer you pass will still point at the same place when the function is through with it. -- _ |__ Alex Matulich (alex@bilver.UUCP) /(+__> Unicorn Research Corp, 4621 N Landmark Dr, Orlando, FL 32817 //| \ UUCP: ...uunet!tarpit!bilver!alex ///__) bitnet: IN%"bilver!alex@uunet.uu.net"
