FozaMemoryManager

public FozaMemoryManager()

Method Details

getPidByPackages

public static int getPidByPackages(String[] games)

Get a best match pid from the specific package names or process names. var gameOrAppProcessNames = new String[] {"com.roblox.client", "com.roblox.client:service"}; var pid = FozaMemoryManager.getPidByPackages(gameOrAppProcessNames);

Parameters:

games - package names or process names array

Returns:

best match pid, 0 if not found

writeMemory

public static void writeMemory(FozaMemoryManager.MemoryControllerHandler handler,
 long offset,
 byte[] ba)

Write a specific process memory with a memory handler.

Parameters:

handler - MemoryControllerHandler which obtained by beginModifyMemory(String, String, boolean)

offset - offset based on the base address

ba - data want to write, size is the byte array length

readMemory

public static byte[] readMemory(FozaMemoryManager.MemoryControllerHandler handler,
 long offset,
 int size)

Read bytes from a specific process's memory with a memory handler.

Parameters:

handler - MemoryControllerHandler which obtained by beginModifyMemory(String, String, boolean)

offset - offset based on the base address

size - read memory segment length

Returns:

bytes, length base on the size that given.

closeHandle

public static void closeHandle(FozaMemoryManager.MemoryControllerHandler handler)

Close a memory controller handler

Parameters:

handler - MemoryControllerHandler which obtained by beginModifyMemory(String, String, boolean)

beginModifyMemory

public static FozaMemoryManager.MemoryControllerHandler beginModifyMemory(String soLibrary,
 int gamePid,
 boolean isModifyBssSegment)

Parameters:

gamePid - integer value of the process id (pid)

See Also:

• beginModifyMemory(String, String, boolean)

beginModifyMemory

public static FozaMemoryManager.MemoryControllerHandler beginModifyMemory(String soLibrary,
 String gamePid,
 boolean isModifyBssSegment)

Obtain a memory handler from a specific process

Parameters:

soLibrary - Can be empty (""), when empty then base address will be zero, otherwise will be the so base address.

gamePid - Process ID, can be {@value "self"}.

isModifyBssSegment - If true then the base address will be the bss segment like [libxxx.so:bss], otherwise the common base address of a ELF file.

Returns:

Memory controller handler, nullable.
