Using text file with GScanner

[Stephan Meszaros <meszaros cae ca>]

Hi, I am new to GTK+ and I am using it to develop a little GUI app to
download some data through the parallel port of a pc.
I am using the WIN 32 libraries with Visual C++ 6.0 and so far so good =
for
the GUI part.
Now I am trying to use the GScanner from GLIB  to parse my data and it =
is
working fine if I use a variable containing the text to parse.
The problem I have it's when I try to set-up the scanner to use a text =
file
This what I have done and I am getting the following message " test =
text:1:
error: unexpected end of file, expected symbol "
Can someone help me?

Thank you!
