Re: [hylafax-users] Possible incomplete data reported by ai.record function

[Davide Pagnin <pagnin@xxxxxxxxxxxxxx>]

	Hi Lee

I've done extended debugging and found what was causing my problem:

In the file util/Str.h

there is the definition of fxStr (and status is defined as a fxStr).

The indata field (used to avoid malloc) has fixed dimension of 100.

As you can see the status response:

COMREC invalid response received to PPS. {E146}; Giving up after 3
attempts to send same page

has a length greater than 100.

This would not be a problem, I admit, unless (as was my case) you are
modifying hylafax code to put an extra status information at the
beginning of the string before calling ai.record.

That said, before trying to reproduce the problem on a system with an
unpatched hylafax version, I was not able to understand how the problem
was generated.

What has misleaded me was the fact that I can only use fxStr operation
that has as a second part operator a fxStr of less than 100 bytes.

Sorry for the wrong conclusion.

Anyway, Do you think that I can modify to 200 the indata size without
inappropriate side effect?

I need to keep those status information at the beginning of the status
string.

Regards

Davide
