C extern function returns incorrectly

[tunghn1]

Hi,

Previously on my programming project,

The returnValue in Init.cpp is about 4.1. When it is returned to the main function, it is 0.

Why is my returnValue different in Get() in Init.cpp and main.c?

Any helps would be very much appreciated.

Thanks.

StartTask1() never reads returnValue. It could be that the compiler is simply not doing the store because it figures it's impossible for any code to ever get its value.

What difference does it make if returnValue is zero or not if the code never uses the value for anything?

Thanks. I solved it. Just put a declaration of get in the main.
