I feel a duty to remind, in the most positive and friendly tone:
The author of the referred code acts in his actual area of competence
(C libraries and standards).
The comments here on the C library code and standard compliance come from
developers having a different competence area (multimedia programming).
As bright as the people here are, they land in a foreign area, which
accidentally leads to statements like the above.
