Compare a portion of two strings ignoring case
The strncmp() function compares at most the first \n characters of the two
strings \a s1 and \a s2, ignoring the case of the characters.  It returns
an integer less than, equal to, or greater than zero if (the prefix of) \a
s1 is found, respectively, to be less than, to match, or be greater than
(the prefix of) \a s2.
Compare a portion of two strings ignoring case The strncmp () function compares at most the first \ n characters of the two strings \ a s1 and \ a s2 ignoring the case of the characters . It returns an integer less than equal to or greater than zero if ( the prefix of ) \ a s1 is found respectively to be less than to match or be greater than ( the prefix of ) \ a s2 .
