Hi Chaz Daly here,
I'm the originator of this thread. Thanks to all for the help...
Brian Jackel's fix worked best. Here are the specifics...
I created files using Labview 3.0.1. The files consist of
a 6 line ASCII header (the header values can be positive
or negative so the header length is variable) followed by
image data. The number of pixels being contained in the header.
I tried reading the header in in a variety of ways and then, using
FSTAT, tried to pick up reading the binary (image) data where the
header left off. Problem was that the pointer returned by FSTAT
would sometimes be way past the end of the header.
Brian told me to set my BUFSIZE = 0 on opening the file...it worked!
Again, thanks to everybody for the help...
