Method Detail

VirtualAllocEx

com.sun.jna.Pointer VirtualAllocEx(com.sun.jna.platform.win32.WinNT.HANDLE process,
                                   com.sun.jna.Pointer address,
                                   int size,
                                   int allocationType,
                                   int protect)

Changes the state of memory in a given process.

Parameters:

process - The process in which to change the memory.

address - The address of the memory to allocate.

size - The size of the allocated region.

allocationType - The allocation type.

protect - The memory protection.

Returns:

A pointer to the allocated memory.

VirtualFreeEx

boolean VirtualFreeEx(com.sun.jna.platform.win32.WinNT.HANDLE process,
                      com.sun.jna.Pointer address,
                      int size,
                      int freeType)

Frees memory in the given process.

Parameters:

process - The process in which to change the memory.

address - The address of the memory to free.

size - The size of the freed region.

freeType - The freeing type.

Returns:

true if the operation succeeded.

CreateRemoteThread

@MaybeNull
com.sun.jna.platform.win32.WinNT.HANDLE CreateRemoteThread(com.sun.jna.platform.win32.WinNT.HANDLE process,
                                                                      @MaybeNull
                                                                      com.sun.jna.platform.win32.WinBase.SECURITY_ATTRIBUTES securityAttributes,
                                                                      int stackSize,
                                                                      com.sun.jna.Pointer code,
                                                                      com.sun.jna.Pointer argument,
                                                                      @MaybeNull

An alternative implementation of Kernel32.CreateRemoteThread(WinNT.HANDLE, WinBase.SECURITY_ATTRIBUTES, int, WinBase.FOREIGN_THREAD_START_ROUTINE, Pointer, WinDef.DWORD, Pointer) that uses a pointer as the code argument rather then a structure to avoid accessing foreign memory.

Parameters:

process - A handle of the target process.

securityAttributes - The security attributes to use or null if no attributes are provided.

stackSize - The stack size or 0 for using the system default.

code - A pointer to the code to execute.

argument - A pointer to the argument to provide to the code being executed.

creationFlags - The creation flags or null if no flags are set.

threadId - A pointer to the thread id or null if no thread reference is set.

Returns:

A handle to the created remote thread or null if the creation failed.

GetExitCodeThread

boolean GetExitCodeThread(com.sun.jna.platform.win32.WinNT.HANDLE thread,
                          com.sun.jna.ptr.IntByReference exitCode)

Receives the exit code of a given thread.

Parameters:

thread - A handle to the targeted thread.

exitCode - A reference to the exit code value.

Returns:

true if the exit code retrieval succeeded.
