将u_int32_t转换为char **

Question

I am working with functions (c language )and there is a variable declared as u_int32_t value;

and I have to pass it to a function which takes argument of type (char **)

I have tried using value[0] etc but it doesnot work.

How to go ahead with typecasting? or

Is there any workaround for it?

Answer 1

A (char **) type almost certainly means a pointer (*) to either one or else an array of C-string (which is a pointer to its first char, or a char * ).

The most likely solution is hence to generate a C-string from your integer value, and pass a reference to it to the function you want to call with a char ** argument. Whether this solves your problem depends on the details of this function and what you are trying to achieve.
