#165311 - volatile applies to data - not functions Responding to: ???'s previous message |
Just looking again at my earlier reply:
Jacob Boyce's interviewer said: if you wanted a delay loop, that you would use the STATIC VOLATILE in front of the subroutine (sic) so that the delay loop would not get optimized Andy Neil said:
Yes, you could use volatile to prevent an otherwise useless loop from being optimised away - but static has nothing whatsoever to do with it! Just to clarify that you would apply the volatile modifier to the definition of the loop counter - not to the function containing it. |

| if it is irrelevant, then why ... | 01/01/70 00:00 | |
| Because they are not equivalent | 01/01/70 00:00 | |
