RtkOpenEvent

RtkOpenEvent returns a handle to an existing named RTSS event object.

Syntax

NTSTATUS RtkOpenEvent(
    RTSSINST RtssInst,
    PHANDLE EventHandle,
    ULONG DesiredAccess,
    BOOLEAN InheritHandle,
    PUNICODE_STRING Name
);

Parameters

RtssInst

An RTSSINST value returned from a call to RtkRtssAttach or RtkRtssAttachEx. Must pass in a valid RTSSINST value or the call will fail with STATUS_INVALID_PARAMETER.

EventHandle

A pointer to a handle that will receive a handle to the existing event object. Must pass in a valid pointer to a handle or the call will fail with STATUS_INVALID_PARAMETER.

DesiredAccess

Ignored. The desired access to the event object.

InheritHandle (ignored)

If this value is TRUE, processes created by this process will inherit the handle. Otherwise, the processes do not inherit this handle.

Name

A pointer to a PUNICODE_STRING specifying the name of the event object. The name is limited to 260 characters and can contain any character except the backslash path-separator character (\). Name comparison is case-sensitive.

Return Value

RtkOpenEvent returns STATUS_SUCCESS on success or on failure one of the following NTSTATUS error codes is possible:

• STATUS_INVALID_PARAMETER
• STATUS_UNSUCCESSFUL
• STATUS_INVALID_HANDLE
• STATUS_NO_SUCH_DEVICE

Remarks

RtkOpenEvent enables multiple processes to open handles of the same event object. The function succeeds only if some process has already created the event with RtkCreateEvent. The calling process can use the returned handle in any function that requires a handle of an event object, such as a wait function.

Use RtkCloseHandle to close the handle. The system closes the handle automatically when the process terminates. The event object is destroyed when its last handle has been closed.
