I've read on stackoverflow that some C functions are 'obsolete' or should be 'avoided'. Can you please give me some examples of this kind of functions + the reason why.

gets : can cause buffer overflows.
strtok : is not thread safe (Question: Are C functions thread-safe anyways ?)

This question, asked this morning, made me wonder which features you think are missing from the C++ Standard Library, and how you have gone about filling the gaps with wrapper functions.
