    string tokenizer

    I am trying to find a file type through the file extension. I am trying to use string tokenizer to get the file type. How do i use strtok. what i have done is

    Code:
    char * temp = strtok(filename, ".");
    The things is how do i get the file extension by its self? Some files have '.' in the filename, but i am only interested in the last few characters after the last '.'

    Any hints?

    thanks

    Why bother tokenizing? Just use strrchr, and it'll give you the last occurance of the character in the string.

    Actually I suggested strrchr, to find the last occurance.
