I am afraid it doesn't chime with my interests, but if the code gets into better shape it could be taken up by others.

Thanks for another bit of clean-up.

How do you think about to encapsulate error detection and corresponding exception handling as a reusable aspect in your software?

Thanks for drawing attention to the code in exportmidi.c - I have deleted it since it is just orphan code. I didn't manage to glean what aosd was glancing at the link you gave, but Denemo is some very ancient C code buried under an accretion of newer C and with a scheme layer added, not very promising territory for a new approach to coding.

Thanks for this reopen of the bug report.

Would you like to check return values from functions like the following in the source file "exportmidi.c"?

  • putc ⇒ midi_byte
  • malloc ⇒ midi_change_event

Are you interested to apply aspect-oriented software development?

Hmm, I obviously don't understand the issues here, so I had better leave this for others. It is not a hot topic, since no-one is uploading their additions to Denemo via this mechanism (in fact since denemo.org changed it may not even be possible).

I'm sorry. - I do not see that this open issue was improved with corresponding error detection and exception handling.

I find that a function like "process_http" is also an update candidate because of the unchecked return value from the write() call.

the first of these has gone
the second is being returned to the scheme caller.

I have looked at a few source files for your current software. I have noticed that some checks for return codes are missing.

Would you like to add more error handling for return values from functions like the following?
