How to extract filename from path

Question

There should be something elegant in Linux API/POSIX to extract base file name from full path

Answer 1

template
charType* getFileNameFromPath( charType* path )
{
    if( path == NULL )
        return NULL;

    charType * pFileName = path;
    for( charType * pCur = path; *pCur != '\0'; pCur++)
    {
        if( *pCur == '/' || *pCur == '\\' )
            pFileName = pCur+1;
    }
    
    return pFileName;
}

call: wchar_t * fileName = getFileNameFromPath < wchar_t > ( filePath );

(this is a c++)
