The Embedded Way - The volatile keyword in C

[yashesvii]

I don't know if I should say but I never thought how the volatile keyword will change the context with it's placement! This was really crazy! Thank you!

[mohamedel-hadidy]

to sum it up, the volatile keyword prevents the variable from getting cached

Thanks for the awesome explanation

Fantastic; it's great explanation of C++ features that are usually shoved in the back. I love your video!

Is there an embedded course that Siemens has anywhere online?

Hoping my question is not stupid.


//program 1
volatile int *x = new int;
*x = 5;
write(anybinaryfile, &x, sizeof(int*));
while(1);


//program 2
volatile int *y;
read(anybinaryfile, &x, sizeof(int*));
printf("%d", *y);


/* should this work??? if run program 2 before shutting program 1.
As when I tried to run program 2, it returned core dump. */
