STRDUP(3)		    Library Functions Manual		     STRDUP(3)

NAME
       strdup, strndup -- save a copy of a string

LIBRARY
       Standard	C Library (libc, -lc)

SYNOPSIS
       #include	<string.h>

       char *
       strdup(const char *str);

       char *
       strndup(const char *str,	size_t len);

DESCRIPTION
       The  strdup()  function	allocates  sufficient memory for a copy	of the
       string str, does	the copy, and returns a	pointer	to it.	The memory  is
       allocated  with	malloc(3)  and should be released with free(3) when no
       longer needed.

       The strndup() function copies at	most len characters  from  the	string
       str always NUL terminating the copied string.

RETURN VALUES
       If  insufficient	memory is available, NULL is returned and errno	is set
       to ENOMEM.  Otherwise,  the  strdup()  family  of  functions  return  a
       pointer to the copied string.

SEE ALSO
       free(3),	malloc(3), wcsdup(3)

       The   strndup()	 function   is	 specified  by	IEEE  Std  1003.1-2008
