compare two strings, up to a given length
#include <string.h>
int strncmp( const char *s1,
const char *s2,
size_t n );
int _fstrncmp( const char __far *s1,
const char __far *s2,
size_t n );
The strncmp() and _fstrncmp() functions compare no more than n characters from the string pointed to by s1 to the string pointed to by s2.
The _fstrncmp() function is a data-model-independent form of the strncmp() function that accepts far pointer arguments. It is most useful in mixed memory model applications.
| Value | Meaning |
|---|---|
| < 0 | s1 is less than s2 |
| 0 | s1 is equal to s2 |
| > 0 | s1 is greater than s2 |
strcmp(), stricmp(), strnicmp()
#include <stdio.h>
#include <string.h>
void main()
{
printf( "%d\n", strncmp( "abcdef", "abcDEF", 10 ) );
printf( "%d\n", strncmp( "abcdef", "abcDEF", 6 ) );
printf( "%d\n", strncmp( "abcdef", "abcDEF", 3 ) );
printf( "%d\n", strncmp( "abcdef", "abcDEF", 0 ) );
}
produces the output:
1 1 0 0
