Re: about gawk |& operator and getline on HPUX11

Hallo,

On Wed, 22 May 2002 10:55:49 +0800, Zhao Xiang reported:
> When I test the following simple programs, I got an error:

I suspect that the problem is that return value of function optimal_bufsize
is int while it should be size_t (which is at least unsigned int, sometimes
even long).

I've prepared two patches:

- gawk-3.1.1-optimal_bufsize_size_t.patch

If this patch works, it should be accepted for gawk-3.1.2
Please do "touch awkgram.c" a second after applying the patch so that
make won't try to call yacc/bison.

- gawk-3.1.1-optimal_bufsize_hack.patch

This patch cruel hack prevents optimal_bufsize fromreturning more than 24 KB.
It may solve your problem though I'd say it's not suitable for including
to the distribution tree.

Both these patches are attached.
Both should also (with some offsets and fuzz) work with gawk-3.1.0 sources.

I tried to reproduce the error with gcc 2.7.2.3 with HPUX 10.20.
But gawk worked as expected.
So I cannot tell which of the above patches works (if any).

I'd be very glad if you sent us the information whether the patches (esp. the
first one) work or not.
