SYNOPSIS

       #include <string.h>

       char *strdup(const char *s);

       char *strndup(const char *s, size_t n);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       strdup(): _SVID_SOURCE || _BSD_SOURCE || _XOPEN_SOURCE >= 500
       strndup(), strdupa(), strndupa(): _GNU_SOURCE

DESCRIPTION

       The  strdup()  function  returns  a  pointer to a new string which is a

       The   strndup()  function  is  similar,  but  only  copies  at  most  n
       characters.  If s is longer than n, only n characters are copied, and a
       terminating null byte (’
