Opens an existing named semaphore object
#include <WinAPIProc.au3>
_WinAPI_OpenSemaphore ( $sSemaphore [, $iAccess = 0x001F0003 [, $bInherit = False]] )
| $sSemaphore | The name of the semaphore to be opened. Name comparisons are case sensitive. |
| $iAccess | [optional] The access to the semaphore object. The function fails if the security descriptor of the specified object does not permit the requested access for the calling process. This parameter can be one of the following values. $SEMAPHORE_ALL_ACCESS (Default) $SEMAPHORE_MODIFY_STATE |
| $bInherit | [optional] Specifies whether inherites the handle by a processes, valid values: True - The processes created by this process will inherit the handle. False - The processes do not inherit this handle (Default). Constants are defined in APIProcConstants.au3 |
| Success: | The handle to the semaphore object. |
| Failure: | 0, call _WinAPI_GetLastError() to get extended error information. |
The function succeeds only if some process has already created the semaphore by using the _WinAPI_CreateSemaphore()
function. The calling process can use the returned handle in any function that requires a handle to
a semaphore object.
