Routine Description:

    This routine is called whenever we have a DLL_PROCESS_ATTACH to the DLL

    checks if there is an environment variable called ACSLAN_DEBUG_FLAGS, and
    loads whatever it finds (as a 32-bit hex number) into AcslanDebugFlags

    checks if there is an environment variable called ACSLAN_DUMP_FILE. If
    there is, then output which otherwise would have gone to the terminal
    goes to the file. The file is opened in "w" mode by default - open for
    write. Current file is destroyed if it exists

    If there is an environment variable called ACSLAN_DUMP_FILTER then this is
    loaded into the AcslanDumpCcb array. This is a string of numbers, the
    position of which corresponds to the CCB command. For each position, 1
    means dump the CCB and 2 means dump the CCB and its parameters. This is an
    additional filter control over that contained in ACSLAN_DEBUG_FLAGS which
    allows control on a per CCB basis. Example:

        ACSLAN_DUMP_CCB=1x0221

    means:

        for CCB 0 (DIR.INTERRUPT) dump the CCB only (no parameter table anyway)
                1 (???) don't do anything (x==0)
                2 (???) don't do anything (x==0)
                3 (DIR.OPEN.ADAPTER) dump the CCB and parameter table
                4 (DIR.CLOSE.ADAPTER) dump the CCB and parameter table
                    (no parameter table, doesn't matter)
                5 (DIR.SET.MULTICAST.ADDRESS) dump the CCB

    etc. We currently recognize up to CCB command 0x36 (54, PURGE.RESOURCES)

Arguments:

    None.

Return Value:

    None.

/*++

Routine Description:

    Dumps a CCB and any associated parameter table. Also displays the symbolic
    CCB command and an error code description if the CCB is being returned to
    the caller. Dumps NT format CCBs (flat 32-bit pointers)

Arguments:

    Ccb         - flat 32-bit pointer to CCB2 to dump
    DumpAll     - if TRUE, dumps parameter tables and buffers, else just CCB
    CcbIsInput  - if TRUE, CCB is from user: don't display error code explanation

Return Value:

    None.
