Append a specified number of characters to a character array.

This function is compatible with the following targets:

ANSI

BeOS

EMB/RTOS

Mac OS

Palm OS

Win32

#include <string.h>

char *strncat(char *dest, 

Parameters for this facility are:

dest	char *	The destination string
source	const char *	The source to append
n	size_t	The maximum length to append

The strncat() function appends a maximum of n characters from the character array pointed to by source to the character array pointed to by dest. The dest argument must point to a null terminated character array. The source argument does not necessarily have to point to a null terminated character array.

If a null character is reached in source before n characters have been appended, strncat() stops.

When done, strncat() terminates dest with a null character ('\0').

strncat() returns the value of dest.

"strcat"

#include <string.h>
#include <stdio.h>

int main(void)
{
	static char s1[100] = "abcdefghijklmnopqrstuv";
	static char s2[] = "wxyz0123456789";

	strncat(s1, s2, 4);
	puts(s1);

	return 0;
}
Output:
abcdefghijklmnopqrstuvwxyz
