Completion of error handling

[elfring]

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

• malloc ⇒ conn_create
• pthread_cond_init ⇒ slot_init_updater

I'm closing this for the changes were made:

• cv_malloc does global error handling
• pthread_cond_init

Feel free to reopen it.

I suggest to avoid ignorance of return values a bit more.
Would you like to detect every error situation as early as possible?

[tevino]

You are right about error handling. We'll try our best to

detect every error situation as early as possible

But it is a lot of work, PRs of that type are very welcome and will be appreciated. :)

• How do you think about to improve static source code analysis also for your software?

• Are you interested to apply aspect-oriented software development?

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