Question

while(((long)(1000*ratio*((long)clock()-(long)t0))%100)/1000)<Data_Read_Rate);

The above line is generating the following error:
“Syntax Error before < token”.

Why is this error coming up?

I use MINGW32 for development(GCC compiler).

Thanks…

Answer 1

One paren is missing on the left. This will parse:

while ((((long)(1000*ratio*((long)clock()-(long)t0))%100)/1000)<Data_Read_Rate);

Aside from the parse issue:

• Use an editor that highlights matching parentheses 🙂
• Why not calculate the time remaining until the data read rate has dropped sufficiently, and call sleep()? That’s nicer on the processor.

Also, considering your use of the % operator, you may want to have the extra paren placed like so (I’m assuming ratio is not an integer), because the % operator requires integer operands:

while (((long)(1000*ratio*(((long)clock()-(long)t0))%100)/1000)<Data_Read_Rate);

(But does that make sense on a semantic level? Chop it up!)
