Can you use thread local variables inside a class or structure

Question

Like this.

struct some_struct
{
 // Other fields
 .....
 __thread int tl;
}

I\'m trying to do that but the compiler is giving me this error

Answer 1

You can also specify the struct itself as thread local. For example;

#include 

thread_local struct gl_i_t{
    int a; 
    int b;
}GL_i_t;

Then you can use GL_i_t variables inside thread.
