Normally semaphore techniques are used when handling multiple resources. In your case you can use Mutex locks. Because you have only one file descriptor.

Actually it is not possible to pass because we cannot predict when the interupt comes but if you store whatever data you want to pass in register just after starting your program (like in R0, R1..) and use this register value when interrupt get call, by this way you can pass.

A function prototype tells the compiler what kind of arguments a function is looking to receive and what kind of return value a function is going to give back. This approach helps the compiler ensure that calls to a function are made correctly and that no erroneous type conversions are taking place.

Int foo(int); // This is func. prototype//Below is func. definitionint foo(int param) { int ret_val; retval=param*100;// return ret_val;}A prototype enables the compiler to know the existence of a certain function somewhere in the program.Whereas the function definition tells it's logic.
