Question

It has been a while since I messed with C/C++, and my memory of the available functions for working with a char* has gone out the window.

I currently use the following code to get the Current Working Directory…

char *path = NULL;
size_t size = 0;

path = _getcwd(path, size);
Msg("Current Working Directory: %s\n", path);

However, I need to take this path, then cut off the last directory, dropping it to the previous directory. It currently stores something like “C:/srcds/orangebox” in path, and I need to drop the last directory from this to get the correct path. In this case, it would be “C:/srcds”.

What is the best way to do this with a char*? Please don’t suggest to use strings. I know this is immensely easier, but the SDK I use revolves heavily around char* instead, so I try to stick with this for readability.

Okay – to keep your life complicated..

1. use strrchr to find the last \
2. use memcpy (unless you have strncpy) to copy number of characters to that point.

I should add that 1. will return the last \, so you if your path is like C:/foo/bar/, it will stop at / – so you’ll have to do some boundary checks… I did say “to keep your life complicated”…
