#include <string.h> int strncmp( const char *str1, const char *str2, size_t count );
The strncmp() function compares at most count characters of str1 and str2. The return value is as follows:
| Return value | Explanation |
|---|---|
| less than 0 | ''str1'' is less than ''str2'' |
| equal to 0 | ''str1'' is equal to ''str2'' |
| greater than 0 | ''str1'' is greater than str2'' |
If there are less than count characters in either string, then the comparison will stop after the first null termination is encountered.
