I would, but what you say does _not_ explain the discrepancy that
I observe to be a bug. [Also, as you'll see what you say is
wrong on its own]
orion:libc$ ./filestream
Read: testorion:libc$
orion:libc$ ./memstream
read error!
The file "filestream" uses is exactly 4 bytes long, and consists
of the characters "test"
orion:libc$ hexdump testfile
0000000 6574 7473
0000004
So, there doesn't have to be an end-of-line character at the end
of the last line in a file to make fgets work all right!!
This might be a bug that depends on platform/version of the development
software. Which version are you using? I'm using latest glibc in woody,
and the architecture is i386
I could write a workaround if the code I worked on was to be exclusive
for memstreams but that isn't the case. For some reason, it would
be better if the same code would work for the mem stream as well
as the file stream.
Could you please verify this discrepancy? You need to compile and run
both files.
Thanks for your attention!
