Completion of error handling

[elfring]

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

• dup2 ⇒ main
• printf ⇒ print_help

If they indeed cause problems, I will fix them.

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

[wangyu-]

I will add an assert for dup2. For printf it looks overkill.

For functions which fails frequently(such as socket related) I did add a lot of error handling codes.

[elfring]

I would generally prefer a safe condition check there instead of a macro call with code which can be supressed.

• Are you interested to apply aspect-oriented software development?
• Would you like to encapsulate error detection and corresponding exception handling as a reusable aspect in your software?

Though I currently dont suppress assert(since they didnt show noticeable performance difference), maybe its a good idea to define a custom assert for the codes which should never be suppressed.

Looks interesting but a bit pedantic😂

:crystal_ball:

• How pedantic can software development become when you fiddle still with mentioned assertions?
• Would you like to try any aspect libraries out?
