strcmp, strncmp — compare two strings
#include <string.h>
int
strcmp( |
const char * | s1, |
| const char * | s2); |
int
strncmp( |
const char * | s1, |
| const char * | s2, | |
| size_t | n); |
The strcmp() function
compares the two strings s1 and s2. It returns an integer less
than, equal to, or greater than zero if s1 is found, respectively, to
be less than, to match, or be greater than s2.
The strncmp() function is
similar, except it only compares the first (at most)
n characters of
s1 and s2.
The strcmp() and
strncmp() functions return an
integer less than, equal to, or greater than zero if
s1 (or the first
n bytes thereof) is
found, respectively, to be less than, to match, or be greater
than s2.
