#89235 - I'm wrong - Damn! Responding to: ???'s previous message |
"No, it's wrong. The arguments are not passed on the stack, they are passed in a fixed 15 byte area of RAM. Problems caused by passing too many arguments occur when that 15 byte area is exhausted."
Yep, looks like you are right. A 15 byte area set aside especially for printf(). I know of the 15 byte limit, and have most certainly experienced the frustration of not. I had hoped to illuminate a possible cause for the poster's difficulties, but have to concede that I have failed to do so, since I had the 15 byte buffer's location very wrong. Regards, Murray R. Van Luyn. |
