NAME

strcat, strncat - concatenate two strings
 

SYNOPSIS

#include <string.h>

char *strcat(char *dest, const char *src);

char *strncat(char *dest, const char *src, size_t n);

DESCRIPTION

The strncat() function is similar, except that

*

it will use at most n characters from src; and

*

src does not need to be null terminated if it contains n or more characters.

As with strcat(), the resulting string in dest is always null terminated.

If src contains n or more characters, strncat() writes n+1 characters to dest (n from src plus the terminating null byte). Therefore, the size of dest must be at least strlen(dest)+n+1.

A simple implementation of strncat() might be:

char*
strncat(char *dest, const char *src, size_t n)
{
    size_t dest_len = strlen(dest);
    size_t i;

    for (i = 0 ; i < n && src[i] != aq\0aq ; i++)
        dest[dest_len + i] = src[i];
    dest[dest_len + i] = aq\0aq;

    return dest;
}
