The size of struct thread_info in the ARM architecture?

Hi,

What bytes is the size of struct thread_info in the linux kernel for the ARM architecture?

Code:

printk("struct thread_info size : %d\n", sizeof(struct thread_info));

Is it different for each versions of the ARM architecture?

Thank you.

thread_info for ARM is defined in <arch/arm/include/asm/thread_info.h>. There is only one thread_info structure for all the ARM versions.

Thank you for your reply.

I want to know the size of struct thread_info for the ARM architecture.

Simply #include the appropriate header file from the kernel source tree into your program, and use the sizeof operator against the structure typedef.

This is why kernel header files are made available. These will be the actual structure definitions used by the kernel on that machine as-built. Although userland doesn't have direct access to the structures themselves, you are free to know all about them.
