Question

I have a old program in which some library function is used and i dont have that library.

So I am writing that program using libraries of c++. In that old code some function is there which is called like this

*string = newstrdup(‘Some string goes here’);

the string variable is declared as char **string;

What he may be doing in that function named ‘newstrdup’ ? I tried many things but i dont know what he is doing … Can anyone help

Answer 1

there has to be a reason that they wrote a ‘new’ version of strdup. So there must be a corner case that it handles differently. like perhaps a null string returns an empty string.

litb’s answer is a replacement for strdup, but I would think there is a reason they did what they did.

If you want to use strdup directly, use a define to rename it, rather than write new code.
