I accidentally hit submit too early.
I tried changing the code in posixmodule.c to use lseek(), something like the
following:
offset = lseek( in, 0, SEEK_CUR );
do {
ret = sendfile(...);
} while( ... );
lseek( in, offset, SEEK_SET );
... however, in addition to readfile not advancing the file pointer it also
doesn't seem to cause an EOF condition. In my first attempt at the above I was
doing this after the loop:
lseek( in, offset, SEEK_CUR );
... and it just kept advancing the file pointer well beyond the end of the file
and sendfile() had absolutely no qualms about reading beyond the end of the
file.
I even tried adding a read() after the 2nd lseek to see if I could force an EOF
condition but that didn't do it.
