Question

anisha@linux-y3pi:~> g++ conditionVarTEST.cpp -Wall

conditionVarTEST.cpp: In function ‘int main()’:
conditionVarTEST.cpp:33:53: error: invalid conversion from ‘void*         


        

Answer 1

And as you are using a C++ compiler, you should use a function with C binding, as pthread_create expects a C function:

extern "C" void* functionA (void*);

C++ and C may have the same calling conventions on your current platform, but there is no guaranty, that this will be the case on other platforms or will be so in the future.
