Hello,
I am having trouble increasing the size of a UDP socket buffer using TI's POSIX API. I tested my code in the UDP example project provided in TI's SDK (C:\ti\simplelink_cc32xx_sdk_4_40_00_07\examples\rtos\CC3235SF_LAUNCHXL\ns\udpecho), but even there the setsocketopt() function fails. Below is a snippet of my code. Most of the code is provided in the example project. Thank you!
server = socket(AF_INET, SOCK_DGRAM, 0);
if (server == -1) {
Display_printf(display, 0, 0, "Error: socket not created.\n");
goto shutdown;
}
memset(&localAddr, 0, sizeof(localAddr));
localAddr.sin_family = AF_INET;
localAddr.sin_addr.s_addr = htonl(INADDR_ANY);
localAddr.sin_port = htons(arg0);
status = bind(server, (struct sockaddr *)&localAddr, sizeof(localAddr));
if (status == -1) {
Display_printf(display, 0, 0, "Error: bind failed.\n");
goto shutdown;
}
SlNetSock_Winsize_t socketBuffer;
socketBuffer.winSize = 3000;
if(setsockopt(server, SOL_SOCKET, SO_RCVBUF, (uint8_t *)&socketBuffer, sizeof(socketBuffer)) != 0)
{
Display_printf(display, 0, 0, "ERROR -> UDP Handler: failed to change socket buffer size.\n");
}
