NAME
       strncpy - General: Copies a null-terminated character string with a specified limit

SYNOPSIS
       char * strncpy(
	       char *s1,
	       char *s2,
	       int n );

ARGUMENTS
       Specifies  a pointer to a buffer of at least n bytes.  Specifies a pointer to a string (an array of characters terminated by a null charac-
       ter).  Specifies the number of characters to be copied.

DESCRIPTION
       The strncpy routine copies string s2 to buffer s1. The routine stops copying after it copies a null character or  n  characters,  whichever
       comes first.  If the length of s2 as determined by the null character is less than n, the routine pads s1 with null characters.

RETURN VALUES
       The  strncpy  routine  returns a pointer to /NULL at the end of the first string (or to the location following the last copied character if
       there is no NULL). The copied string will not be null terminated if the length of s2 is n characters or more.
