Tag: Is C function case sensitive?

Anything that is case sensitive discriminates between uppercase and lowercase letters . In other words, it means that two words that appear or sound identical but are using different letter cases, are not considered equal.

It is case-insensitive . The behavior is NOT undefined (it is well-defined) if either string is a null ptr. Regular strncmp() has undefined behavior if either string is a null ptr (see: https://en.cppreference.com/w/cpp/string/byte/strncmp).
