Demonstrates how to check to see if a file exists. C++

    // Check to see if a file exists

    // The return value is one of the following values:
    // -1: Unable to check. Examine the LastErrorText to determine the reason for failure.
    // 0: File does not exist.
    // 1: The regular file exists.
    // 2: It exists, but it is a directory.
    // 3: It exists, but it is a symlink (only possible if followLinks is false)
    // 4: It exists, but it is a special filesystem entry type.
    // 5: It exists, but it is an unkown filesystem entry type.
    // 6: It exists, but it is an socket filesystem entry type.
    // 7: It exists, but it is an char device entry type.
    // 8: It exists, but it is an block device entry type.
    // 9: It exists, but it is an FIFO entry type.
