-.SH DESCRIPTION
-The
-.BR strdup ()
-function returns a pointer to a new string which
-is a duplicate of the string
-.IR s .
-Memory for the new string is
-obtained with
-.BR malloc (3),
-and can be freed with
-.BR free (3).
-
-The
-.BR strndup ()
-function is similar, but copies at most
-.I n
-bytes.
-If
-.I s
-is longer than
-.IR n ,
-only
-.I n
-bytes are copied, and a terminating null byte (\(aq\\0\(aq) is added.
-
-.BR strdupa ()
-and
-.BR strndupa ()
-are similar, but use
-.BR alloca (3)
-to allocate the buffer.
-They are available only when using the GNU
-GCC suite, and suffer from the same limitations described in
-.BR alloca (3).
-.SH RETURN VALUE
-On success, the
-.BR strdup ()
-function returns a pointer to the duplicated
-string.
-It returns NULL if insufficient memory was available, with
-.I errno
-set to indicate the cause of the error.
-.SH ERRORS
-.TP
-.B ENOMEM
-Insufficient memory available to allocate duplicate string.
-.SH CONFORMING TO
-.\" 4.3BSD-Reno, not (first) 4.3BSD.
-.BR strdup ()
-conforms to SVr4, 4.3BSD, POSIX.1-2001.
-.BR strndup ()
-conforms to POSIX.1-2008.
-.BR strdupa ()
-and
-.BR strndupa ()
-are GNU extensions.
