int strncmp( char *s1, char *s2, size_t count )

 

char  *s1;         /* a string */

char  *s2;         /* a string */

size_t count;      /* maximum number of characters to copare */

 

 




Synopsis

#include "string.h"

 

The strncmp function compares up to count characters starting at s1 with the string at s2 . If a null-terminator is encountered before count characters are compared, then the comparison stops.

 

 

Parameters

s1 and s2 are null-terminated strings. count is an integer specifying the maximum number of characters to compare.

 

 

Return Value

strncmp returns 0 if the strings are lexographically equal through their first count characters. Otherwise, if the string at s1 is lexicographically less than s2 , then strncmp returns a negative number; if the string at s1 is lexicographically greater than s2 , then strncmp returns a positive number.
