Function

SYNOPSIS

#include <string.h>

char *strncpy(char *s1, const char *s2, size_t n);

DESCRIPTION

The strncpy() function copies up to n characters, including the terminating null character, from the string pointed to by s2 into the buffer pointed to by s1. Once strncpy() has copied n characters to s1, it does not append a terminating null character.
