I am a little unclear about text widget in Motif.  I am trying to figure out
how to access the text widget's text.  I need to access the text because another
program must access it using share memory.  I have look through Dennis Young's
book, and I have look through the Motif reference Guide.  The reference Guide
mentioned that one can access the source text through a resource XmNsource.  I
am not clear on how this can be done.  I only have the motif docs so far, but
nothing I can work with, so I can test or verify anything.  Could someone on
the net answer the following questions.

1. If the source text is in resource, wouldn't it be in a resource file?
   Wouldn't this be a bit slow accessing the drive all the time?  I am still not
   to clear about resource.

2. The reference mentioned that the XmNsource's type is XmTextSource, can
   someone tell me what the structure looks like or where I can look it up?

3. Has anyone play around with sharing the text in a widget with another
   program?  What is your experience.

Thanks.
