Other function implementations could have used extra checks because an API
property was not documented in preferred formats (besides the C source code) so
far.

This update provides chances to improve the software situation for further
libraries and development tools, doesn't it?

Do you distinguish usage categories for these functions?
Examples:
* Constructor
* Destructor
* Action
Is the âprobabilityâ for null pointers different in input parameters there?
(Could this detail be used for another bit of fine-tuning?)
