stdio.h does not recognize FILE *fpointer

I am using IAR embedded workbench software for ARM CORTEX M3 controller. I have already included stdio.h library and it have fopen function like this 

but when i am declaring my file pointer like this

FILE *fpointer;

Its giving me these two errors.

Please share your experience how can i fix it?

  • I think you should ask this in an IAR forum since I think it does have to be with the IDE more than with the Cortex M3. This being an ARM forum, if you are not using an ARM tool like Keil, I don't think nobody is going to be willing to help, at least not from ARM.
