Okay, so I guess not "standards", but someone has already gone to the trouble for you to lay out how a basename function should perform. I can't come up with any better word.

My point was implementations already exist that follow this laid out procedure.

thank you SANE for explaining what i try to imply

Sane you are right there is a standart

That is only standard for MS-Windows operating system. Can't use it in *linx or any other os. So its not standard afterall. But, since you are writing a Windows program there is absolutely no harm in using that function -- just don't get confused between win32 api functions and standard C or C++ functions. The win32 api has hundreds of functions unique to that operating system -- not one of them are standard C/C++ functions.

Maybe it is not for *nix etc. But it is a standart for windows and i asked for windows.but i dont want to argue with you again.you are a billion times more better than me

The easiest way is to start from the back of the string and search for the "\\". This is easy. Once you have the pointer you can display the file name.

(Toggle Plain Text)

int len = strlen(fname);
int pos = len - 1;
char* name = NULL;

while (pos >= 0)
{

    if (fname[pos] == '\\')
    {

        pos++;
        name = fname + pos;
        printf("fname=%s\n", name);

    }

    pos--;

}

Sorry, but I disagree. The easiest way it to use strrchr() so that you don't have to reinvent the wheel.

Yeah, but you have to check to see if the pointer is valid. It is easier to look at each character directly. Anyways, either way can work. My way might be a bit quicker, though. We don't all have to agree.

There is also a _splitpath function, that can help in the OP problem, and some more similar ones.

PathStripPath() is defined in the windows api and is your best bet for win32 and win64 development. i think it was already suggested tho
