    FILE: ftpapi.h

    DESCRIPTION:
        This file contains functions to perform the following 2 things:

    1. WININET WRAPPERS: Wininet APIs have either wierd bugs or bugs that come thru the APIs
    from the server.  It's also important to keep track of the perf impact
    of each call.  These wrappers solve these problems.

    2. FTP STRs to PIDLs: These wrappers will take ftp filenames and file paths
    that come in from the server and turn them into pidls.  These pidls contain
    both a unicode display string and the filename/path in wire bytes for future
    server requests.
