Method Summary

Modifier and Type	Method and Description
WinNT.HANDLE	CreateRemoteThread(WinNT.HANDLE process, WinBase.SECURITY_ATTRIBUTES securityAttributes, int stackSize, Pointer code, Pointer argument, WinDef.DWORD creationFlags, Pointer threadId) 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.
boolean	GetExitCodeThread(WinNT.HANDLE thread, IntByReference exitCode) Receives the exit code of a given thread.
Pointer	VirtualAllocEx(WinNT.HANDLE process, Pointer address, int size, int allocationType, int protect) Changes the state of memory in a given process.
boolean	VirtualFreeEx(WinNT.HANDLE process, Pointer address, int size, int freeType) Frees memory in the given process.

Method Detail

VirtualAllocEx

Pointer VirtualAllocEx(WinNT.HANDLE process,
                       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(WinNT.HANDLE process,
                      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
WinNT.HANDLE CreateRemoteThread(WinNT.HANDLE process,
                                           @MaybeNull
                                           WinBase.SECURITY_ATTRIBUTES securityAttributes,
                                           int stackSize,
                                           Pointer code,
                                           Pointer argument,
                                           @MaybeNull
                                           WinDef.DWORD creationFlags,
                                           @MaybeNull
                                           Pointer threadId)

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(WinNT.HANDLE thread,
                          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.
