Completion of error handling

[elfring]

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

• printf ⇒ printmatches
• strdup ⇒ grokdir

[adrianlopezroche]

For strdup, yes. For printf... why?

[elfring]

I suggest to avoid ignorance of return values a bit more.

• Would you like to detect every error situation as early as possible?
• Do you care for file output failures?

[adrianlopezroche]

Fixed for strdup in grokdir, commit c671a2b.

Dealing with printf seems rather more complicated, as it returns a positive number of bytes read even when output is redirected to /dev/full. I don't know how to get printf to return an error when stdout is full.

[elfring]

Can you get any further software development ideas from the following command example?

elfring@Sonne:~> LANG=C echo X > /dev/full
bash: echo: write error: No space left on device
