                        int dwMilliseconds)
Waits until the specified object is in the signaled state or the time-out interval elapses. To enter an alertable wait state, use the WaitForSingleObjectEx function. To wait for multiple objects, use the WaitForMultipleObjects.

Parameters:
hHandle - A handle to the object. For a list of the object types whose handles can be specified, see the following Remarks section. If this handle is closed while the wait is still pending, the function's behavior is undefined. The handle must have the SYNCHRONIZE access right. For more information, see Standard Access Rights.

If dwMilliseconds is zero, the function does not enter a wait state if the object is not signaled; it always returns immediately. If dwMilliseconds is INFINITE, the function will return only when the object is signaled.
Returns:
If the function succeeds, the return value indicates the event that caused the function to return.

WaitForMultipleObjects

                           int dwMilliseconds)
Waits until one or all of the specified objects are in the signaled state or the time-out interval elapses. To enter an alertable wait state, use the WaitForMultipleObjectsEx function.

Parameters:
nCount - The number of object handles in the array pointed to by lpHandles. The maximum number of object handles is MAXIMUM_WAIT_OBJECTS.
hHandle - An array of object handles. For a list of the object types whose handles can be specified, see the following Remarks section. The array can contain handles to objects of different types. It may not contain multiple copies of the same handle. If one of these handles is closed while the wait is still pending, the function's behavior is undefined. The handles must have the SYNCHRONIZE access right. For more information, see Standard Access Rights.
bWaitAll - If this parameter is TRUE, the function returns when the state of all objects in the lpHandles array is signaled. If FALSE, the function returns when the state of any one of the objects is set to signaled. In the latter case, the return value indicates the object whose state caused the function to return.
dwMilliseconds - The time-out interval, in milliseconds. If a nonzero value is specified, the function waits until the specified objects are signaled or the interval elapses. If dwMilliseconds is zero, the function does not enter a wait state if the specified objects are not signaled; it always returns immediately. If dwMilliseconds is INFINITE, the function will return only when the specified objects are signaled.
Returns:
If the function succeeds, the return value indicates the event that caused the function to return.

GetComputerName

boolean GetComputerName(char[] buffer,
                        com.sun.jna.ptr.IntByReference lpnSize)
Retrieves only the NetBIOS name of the local computer.

Parameters:
buffer - A pointer to a buffer that receives the computer name or the cluster virtual server name. The buffer size should be large enough to contain MAX_COMPUTERNAME_LENGTH + 1 characters.
lpnSize - On input, specifies the size of the buffer, in TCHARs. On output, the number of TCHARs copied to the destination buffer, not including the terminating null character. If the buffer is too small, the function fails and GetLastError returns ERROR_BUFFER_OVERFLOW. The lpnSize parameter specifies the size of the buffer required, including the terminating null character.
Returns:
If the function succeeds, the return value is a nonzero value. If the function fails, the return value is zero. To get extended error information, call GetLastError.

OpenThread

W32API.HANDLE OpenThread(int dwDesiredAccess,
                         boolean bInheritHandle,
                         int dwThreadId)
The OpenThread function opens an existing thread object.

Parameters:
dwDesiredAccess - Access to the thread object. This access right is checked against any security descriptor for the thread.
bInheritHandle - If this parameter is TRUE, the new process inherits the handle. If the parameter is FALSE, the handle is not inherited.
dwThreadId - Identifier of the thread to be opened.
Returns:
If the function succeeds, the return value is an open handle to the specified process. If the function fails, the return value is NULL. To get extended error information, call GetLastError.

OpenProcess

W32API.HANDLE OpenProcess(int fdwAccess,
                          boolean fInherit,
                          int IDProcess)
This function returns a handle to an existing process object.

Parameters:
fdwAccess - Not supported; set to zero.
fInherit - Not supported; set to FALSE.
IDProcess - Specifies the process identifier of the process to open.
Returns:
An open handle to the specified process indicates success. NULL indicates failure. To get extended error information, call GetLastError.

GetTempPath

W32API.DWORD GetTempPath(W32API.DWORD nBufferLength,
                         char[] buffer)
The GetTempPath function retrieves the path of the directory designated for temporary files.

Parameters:
nBufferLength - Size of the string buffer identified by lpBuffer, in TCHARs.
buffer - Pointer to a string buffer that receives the null-terminated string specifying the temporary file path. The returned string ends with a backslash, for example, C:\TEMP\.
Returns:
If the function succeeds, the return value is the length, in TCHARs, of the string copied to lpBuffer, not including the terminating null character. If the return value is greater than nBufferLength, the return value is the length, in TCHARs, of the buffer required to hold the path. If the function fails, the return value is zero. To get extended error information, call GetLastError.
