STRDUP(3)		   Linux Programmer's Manual		     STRDUP(3)

NAME
       strdup, strndup,	strdupa, strndupa - duplicate a	string

SYNOPSIS
       #include	<string.h>

       char *strdup(const char *s);

       #define _GNU_SOURCE
       #include	<string.h>

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

DESCRIPTION
       The  strdup()  function	returns	 a  pointer to a new string which is a
       duplicate of the	string s.  Memory for the new string is	obtained  with
       malloc(3), and can be freed with	free(3).

       The  strndup()  function	 is similar, but only copies at	most n charac-
       ters. If	s is longer than n, only n characters are copied, and a	termi-
       nating NUL is added.

       strdupa	and  strndupa  are  similar, but use alloca(3) to allocate the
       buffer. They are	only available when using the GNU GCC suite, and  suf-
       fer from	the same limitations described in alloca(3).

RETURN VALUE
       The  strdup()  function	returns	a pointer to the duplicated string, or
       NULL if insufficient memory was available.

ERRORS
       ENOMEM Insufficient memory available to allocate	duplicate string.

CONFORMING TO
       SVID 3, BSD 4.3.	 strndup(), strdupa(), and strndupa() are  GNU	exten-
       sions.

SEE ALSO
