STRNCAT

Synopsis

#include <string.h>

char * strncat (char * s1, const char * s2, size_t n)

Description

This function appends (concatenates) string

to the end of string

. At most

char-

acters will be copied, and the result will be null terminated.

must point to a character

array big enough to hold the resultant string.

#include <string.h>

#include <stdio.h>

void

main (void)

{

char buffer[256];

char * s1, * s2;

strcpy(buffer, "Start of line");

s1 = buffer;

s2 = "... end of line";

strncat(s1, s2, 5);

printf("Length = %d\n", strlen(buffer));

printf("string = \"%s\"\n", buffer);

}

STRNCMP, STRNICMP

Synopsis

#include <string.h>

int strncmp (const char * s1, const char * s2, size_t n)

int strnicmp (const char * s1, const char * s2, size_t n)

Description

The

strncmp()

function compares its two, null terminated, string arguments, up to a

maximum of

characters, and returns a signed integer to indicate whether

is less

than, equal to or greater than

. The comparison is done with the standard collating

sequence, which is that of the ASCII character set.

The

strnicmp()

function is the case-insensitive version of this function.
