/*
LocMsg - Say "Yes!" to localization.
Author - Ivan Sintyurin. Copyright (c) 2000. All Rights Reserved.

  I'll be glad if this function helps you to  write  localization
enabled programs. I'll ask of you only one  thing  -  mention  my
copyright notice somewhere in your program (in  the  readme  file
for example).

  The LocMsg function returns a pointer to a string in accordance
with FAR's language settings (taking into account current  user's
settings - feature of FAR 1.63 or newer).

  In the same folder as the plugin there should be a  file  named
"PluginName.msg" containing  the  messages.  This  file's  format
description is available in the template.msg file.

Function parameters:
MsgName - the name of the needed message
Var     - if not NULL then it will receive the wanted string
Len     - if 0 then the whole string is copied to Var

In addition the following global structure should be defined  and
filled:
PluginStartupInfo Info, the following data is taken from it:
Info.RootKey - location of plugin data storage
Info.ModuleName - full path to the plugin
