Details

Process Identifier

A processIdentifier is required to open a process and begin reading or writing memory. This can either be the name of the process, or it's PID:

const processName = 'csgo.exe';
const processId = 1234;

Process Object

When opening a process, an object is returned with details about it.

{ dwSize: 304,
  th32ProcessID: 10316,
  cntThreads: 47,
  th32ParentProcessID: 7804,
  pcPriClassBase: 8,
  szExeFile: "csgo.exe",
  modBaseAddr: 1673789440,
  handle: 808 }

This object is important as the handle property is required to interact further with the process.

Functions

openProcess(processIdentifier[, callback])

• processIdentifier - either the process name, or the ID of the process
• callback - has two parameters:
  • error - error message (if one occurred)
  • processObject - object containing information about the process

returns (if no callback provided): object containing information about the process

Internally opens a handle to the process to be able to interact with it.

// synchronously
const processObject = memoryjs.openProcess(processIdentifier);

// asynchronously
memoryjs.openProcess(processIdentifier, (error, processObject) => {

});

getProcesses([callback])

• callback - has two parameters:
  • error - error message (if one occurred)
  • processes - array of process objects

returns (if no callback provided): array of process objects

Finds all the processes running on the system and returns information about them.

Get all processes:

// synchronously
const processes = memoryjs.getProcesses();

// asynchronously
memoryjs.getProcesses((error, processes) => {

});

closeProcess(handle)

• handle - the handle of the process, retrieved from calling openProcess

Closes the handle on the opened process.

memoryjs.closeProcess(processObject.handle);
