hello,
i was looking at a program someone wrote.
I saw something like that:
name = (char*) strdup(path);

strdup already returns char *, so why do we need casting here?
did he do a wrong thing or am i wrong?

He didn't do anything "wrong" as such, but there isn't any need to cast it.

Only that strdup() isn't a portable function.

Without more code to look at, I can only guess. But my guess is that he didn't include the right header for strdup and casted the result to silence his compiler's warnings about it.
