Mentioning time complexity of sscanf

There has been some blogging and discussion recently, about how sscanf can cause accidental quadratic performance ([1] [2] [3] [4]). Is that something that could/should be mentioned here? --Rchard2scout (talk) 02:05, 3 March 2021 (PST)

Clarifying Conversion Behavior in fscanf

We should add the following paragraph (quote from the current C draft) or equivalent regarding conversion behavior in fscanf:

Unless assignment suppression was indicated by a *, the result of the conversion is placed in the object pointed to by the first argument following the format argument that has not already received a conversion result. If this object does not have an appropriate type, or if the result of the conversion cannot be represented in the object, the behavior is undefined.
