strcmp
() and strncmp
()
functions lexicographically compare the nul-terminated strings
s1 and s2.
strcmp
() and strncmp
()
functions return an integer greater than, equal to, or less than 0, according
to whether the string s1 is greater than, equal to, or
less than the string s2. The comparison is done using
unsigned characters, so that ‘\200
’ is
greater than ‘\0
’.
The strncmp
() function compares not more
than len characters.
strcmp
() and strncmp
()
functions conform to ANSI X3.159-1989
(“ANSI C89”).
strncmp
() always
returns 0.
