Memory leak

Hi,

I build a shared library that uses the libcurl. The used memroy of my
application is growing. The application sends a request every ten
seconds.

I'm using the libcurl as follow:

the first step is to initialize the CURL Pointer the fuchtnion
curl_easy_init(). Using the struct curl_slist for the header.

the second step is to send the request with curl_easy_perform()

at the end using the two functions above to free all the allocated
memory.
curl_slist_free_all()
curl_easy_cleanup()

In order to be able to receive a response from the web-server, the
shared library use the following fuction:
struct MemoryStruct {
 char *memory;
 size_t size;
}

Memoryfunction(void *ptr, size_t size, size_t nmemb, void *data)
{
   INT_32 realsize = size * nmemb;
   struct MemoryStruct *mem = (struct MemoryStruct*) data;;
   
   mem->memory = (INT_8 *) realloc (mem->memory, mem->size + realsize +
1);
   if (mem->memory) {
      memcpy (&(mem->memory[mem->size]), ptr, realsize);
      mem->size += realsize;
      mem->memory[mem->size] = 0;
   }

   return realsize;
}

the application is working without problems only the memory.....
Regardless this measure the used memory is growing only when the libcurl
functions are used. ;-) Is't possible?

Regards.
Karim.
