How to "strcmp" data from gtk_entry?

["george carter" <cglobal25 hotmail com>]

  I'm having a small problem with using the data from a gtk_entry.  I would 
like a user to enter a username and password into a gtk_entry.  I don't have 
a problem with connect the button signals or anything.  I'm calling a 
function which should compare the gtk_entry data with "username" for 
example, but I'm not sure how to approach it.  I figure I would use "strcmp" 
and if it returns false than "set_text_entry" to "user not in database." How 
would I put "data" into the strcmp function? I would just like the simplest 
solution to learn from.  So security in the function isn't a priority right 
now.  Any ideas would be appreciated.  Thanks in advance.
