Re: [Letodb-developers] Important question about sockets

[Miguel A. M. <mig...@ma...>]

We can add on connect

             DWORD value;
             int len = sizeof(value);
             GetSockOpt(SO_SNDBUF, &value, &len);
             if (value < 65536)
             {
                 value = 65536;
                 SetSockOpt(SO_SNDBUF, &value, sizeof(value));
             }
             Socket->SndBufSize = value;
             GetSockOpt(SO_RECBUF, &value, &len);
             if (value < 65536)
             {
                 value = 65536;
                 SetSockOpt(SO_RECBUF, &value, sizeof(value));
             }
             Socket->RecBufSize = value;

and modify structure:

       /* #define HB_SENDRECV_BUFFER_SIZE         1400 */ never use more this

       typedef struct tag_HB_SOCKET_STRUCT
       {
           ULONG sign;
           HB_SOCKET_T com;
           char *errorDesc;
           int errorCode;
           struct sockaddr_in remote;
           LONG count;
           int timeout;
           int timelimit;
           PHB_ITEM caPeriodic;
           DWORD SndBufSize;
           DWORD RecBufSize;
       } HB_SOCKET_STRUCT;
