What is the simplest way to get the directory that a file is in? I\'m using this to find the working directory.

The way of Beetle)

#include

int GetDir(TCHAR *fullPath, TCHAR *dir) {
    const int buffSize = 1024;

    TCHAR buff[buffSize] = {0};
    int buffCounter = 0;
    int dirSymbolCounter = 0;

    for (int i = 0; i < _tcslen(fullPath); i++) {
        if (fullPath[i] != L'\\') {
            if (buffCounter < buffSize) buff[buffCounter++] = fullPath[i];
            else return -1;
        } else {
            for (int i2 = 0; i2 < buffCounter; i2++) {
                dir[dirSymbolCounter++] = buff[i2];
                buff[i2] = 0;
            }

            dir[dirSymbolCounter++] = fullPath[i];
            buffCounter = 0;
        }
    }

    return dirSymbolCounter;
}

Using :

TCHAR *path = L"C:\\Windows\\System32\\cmd.exe";
TCHAR  dir[1024] = {0};

GetDir(path, dir);
wprintf(L"%s\n%s\n", path, dir);
