• getModules(processId: number, callback?): Module[]
  Returns the modules loaded by a process.

• readMemory(handle: number, address: number, dataType: T, callback?): MemoryData | undefined
  Reads a value from a process's memory.

• writeMemory(handle: number, address: number, value: any, dataType: DataType): boolean
  Writes a value to a process's memory.

• findPattern(...)
  Scans memory patterns (multiple overloads).

• callFunction(handle: number, args: any[], returnType: number, address: number, callback?): any
  Calls a function in the process's memory.
