What should be the reason for getting undeclared identifier error for RTCS_FD_ZERO and RTCS_FD_SET?

omkardixit — Wed, 02 Jun 2021 07:19:04 GMT

I'm working on the TCP on the TWR-K70F120m and using MQX RTOS 4.1.0. So basically I was working on some protocol in which I wanted to use select() function. To do the same I have written a small code as follows.

RTCS_FD_ZERO(&rfds);
RTCS_FD_SET(sock,&rfds);

_RTCS_select(sock+1,&read_fds,NULL,NULL,0); //sleep here

The problem is, I'm getting "USE OF UNDECLARED IDENTIFIER" error for the RTCS_FD_ZERO and RTCS_FD_SET. How can i remove this error. Also I have added the following header files

#include <mqx.h>
#include <bsp.h>
#include <rtcs.h>
#include <enet.h>
#include <ipcfg.h>
#include "config.h"

is anything missed here. Any help will be really appreciated!!

Regards,

Omkar

Hi @omkardixit ：

RTCS_FD_SET, RTCS_FD_ZERO are defined in sock_select.c.

Please check whether this file is in your project?

make clean all and try it again.
