[splint-discuss] problem with function inet_ntoa()

[Vishal Bayskar]

Dear All,

 

There is a problem with function inet_ntoa

 

 

Following line is used in the code

 

strcpy (ip_addr, inet_ntoa (((struct sockaddr_in *)
&ifr.ifr_addr)->sin_addr));

 

this line is not called in loop 

 

here ip_addr is declare as

 

static char ip_addr[MAX_IPLEN];

 

 

When I run the splint, it is giving the following warning is displaying 

 

 

New fresh storage (type char *) passed as implicitly temp

    (not released): inet_ntoa(((struct sockaddr_in
*)&ifr.ifr_ifru.ifru_addr)->s

    in_addr)

  A memory leak has been detected. Storage allocated locally is not
released

  before the last reference to it is lost. (Use -mustfreefresh to
inhibit

 

 

Does it really do with inet_ntoa() function ?

 

Like if we read manual of it 

 

We can find the sentence that

 

The  inet_ntoa()  function converts the Internet host address in given
in network byte order to a string in standard numbers-and-dots notation.
The string is returned in a statically allocated buffer, which
subsequent calls will overwrite.

 

Please not that 

inet_ntoa() is called only ones

 

 

Thank in advance 

I really thank for the response that I am getting on this blog.

 

 

 

 

Thanks and Regards
