-    Since glibc 2.10:

-.SH DESCRIPTION
-These functions copy non-null bytes from the string pointed to by
-.I src
-into the array pointed to by
-.IR dst .
-If the source has too few non-null bytes to fill the destination,
-the functions pad the destination with trailing null bytes.
-If the destination buffer,
-limited by its size,
-isn't large enough to hold the copy,
-the resulting character sequence is truncated.
-For the difference between the two functions, see RETURN VALUE.
-.P
-An implementation of these functions might be:
-.P
-.in +4n
-.EX
-char *
-strncpy(char *restrict dst, const char *restrict src, size_t dsize)
-{
-    stpncpy(dst, src, dsize);
-    return dst;
-}
-\&
-char *
-stpncpy(char *restrict dst, const char *restrict src, size_t dsize)
-{
-    size_t  dlen;
-\&
-    dlen = strnlen(src, dsize);
-    return memset(mempcpy(dst, src, dlen), 0, dsize \- dlen);
-}

-.BR strncpy ()

-.SH CAVEATS
-The name of these functions is confusing.
-These functions produce a null-padded character sequence,
-not a string (see
-.BR string_copying (7)).
-For example:
-.P
-.in +4n
-.EX
-strncpy(buf, "1", 5);       // { \[aq]1\[aq],   0,   0,   0,   0 }
-strncpy(buf, "1234", 5);    // { \[aq]1\[aq], \[aq]2\[aq], \[aq]3\[aq], \[aq]4\[aq],   0 }
-strncpy(buf, "12345", 5);   // { \[aq]1\[aq], \[aq]2\[aq], \[aq]3\[aq], \[aq]4\[aq], \[aq]5\[aq] }
-strncpy(buf, "123456", 5);  // { \[aq]1\[aq], \[aq]2\[aq], \[aq]3\[aq], \[aq]4\[aq], \[aq]5\[aq] }
-.EE
-.in
-.P
-It's impossible to distinguish truncation by the result of the call,
-from a character sequence that just fits the destination buffer;
-truncation should be detected by
-comparing the length of the input string
-with the size of the destination buffer.
-.P
-If you're going to use this function in chained calls,
-it would be useful to develop a similar function that accepts
-a pointer to the end (one after the last element) of the destination buffer
-instead of its size.
