isspace!?
-
Hello i'm trying to use this do-while loop but it seems that it doesn't work the way I like it to: char szBuffer[18]; do { serial.Read(szBuffer,nBuflen,&dwBytesRead); szBuffer[dwBytesRead] = '\0'; } while (isspace(szBuffer[0])==0);

Where are you incrementing the loop ??? What is your requirement exactly ??

My question was am I using isspace the right way? should i include or define smth to use isspace? The loop is incremented in the serial.Read(...) function.

Well isspace returns true if it is a white space character, and false if it's a real character. Did you post a code fragment, or was it all the code?

Yeah, that just repeats what I said. How is it "wrong"?

The loop should continue until I have non-space caractert e.g. szBuffer[0] != ' ' or szBuffer[0] != '\r', well, it doesn't...

Maybe i'm a bit stupid but looking at your link still let me confused. I still don't get what am I doing wrong.

Yeah, I was referring to the post "It is wrong"...

So, what's the real problem? Does the loop exit immediately? Could be a timing issue. It doesn't seem like you ever do anything with szBuffer, or maybe you left that code out. Everytime you call serial.Read, it's going to overwrite your szBuffer, and you'll lose what's in it, unless you copy it somewhere.

So what is the value of
szBuffer[0]when the loop terminates?
