How to use IEMSI.H with your own programs to add IEMSI compatibility to
your PEXs.

FastLog/IEMSI creates a text file "IEMSI.HSK" in the Nodes home directory
which contains the IEMSI Handshake packet as it was sent by the remote system
or the string "NOIEMSI".

You can add IEMSI support to your program by including the header file
"IEMSI.H" in your C source and using getiemsi() to interpret the Packet and
set pointers to the fields.

----
int getiemsi()

returns:
        IEMSI_NOTINST   : FastLog/IEMSI Not Installed
        IEMSI_NOTUSED   : Current User not using IEMSI
        IEMSI_AVAILABLE : User logged in with IEMSI and the fields have been
                          filled out.

        You should use the constants above instead of the numbers they
        represent as these could change in future versions of IEMSI.H

        if IEMSI_AVAILABLE has been returned then you can use

        IEMSI_ICI to access the fields.
