Function cpu_instructions_reader::ffi::createInstructionNumberReader

Expand description

Mock constructor

This C function internally calls malloc to allocate a memory to construct InstructionNumberReaderRaw, and returns a pointer to the heap

If there is an error in the creation process, the memory will be free, and the pointer will be set to NULL to return, special attention should be paid
