strncat(3p)
NAME
strncat - concatenate a string with part of another
SYNOPSIS
#include <string.h> char *strncat(char *restrict s1, const char *restrict s2, size_t n);
DESCRIPTION
The strncat() function shall append not more than n bytes (a null byte
and bytes that follow it are not appended) from the array pointed to by
s2 to the end of the string pointed to by s1. The initial byte of s2
overwrites the null byte at the end of s1. A terminating null byte is
always appended to the result. If copying takes place between objects
that overlap, the behavior is undefined.
RETURN VALUE
The strncat() function shall return s1; no return value shall be
reserved to indicate an error.
ERRORS
No errors are defined.
