The strcmpi() function is a built-in function in C and is defined in the “string. h” header file . The strcmpi() function is same as that of the strcmp() function but the only difference is that strcmpi() function is not case sensitive and on the other hand strcmp() function is the case sensitive.

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).28 Nis 2011

To make strncmp case-insensitive, use strncasecmp from #include <strings . h> . strncasecmp can be used in exactly the same way as strncmp. Note that both of these will not deal with unicode characters correctly, but will work just fine in most applications.13 Ağu 2019
