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

     If	insufficient memory is available, NULL is returned and errno is	set to
     ENOMEM.

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

     free(3), malloc(3)

     was added in FreeBSD 7.2.
