| std.descriptor16:rawData () | Get the raw data that this descriptor is containing. |
| std.requestStatus:value () | Retrieve the current value of the request status |
| std.requestStatus:flags () | Retrieve the current flags of the request status |
Fields
| descriptor | Abstract class which allows the containment of data. |
| descriptor8 | Detailed descriptor that is designed to hold 8-bit data. |
| descriptor16 | Detailed descriptor that is designed to hold 16-bit data. |
| requestStatus | Struct holding the status of a request. |
Functions
- std.descriptor8:rawData ()
-
Get the raw data that this descriptor is containing.
Returns:
-
A raw FFI byte array containing data.
- rawUtf16ToString (raw, length)
-
Convert a raw 8-bit C FFI byte array into a 16-bit Unicode string/
Parameters:
- raw The raw byte array to convert.
- length The number of characters that the result string should produce.
Returns:
-
Converted string object.
- std.descriptor16:rawData ()
-
Get the raw data that this descriptor is containing.
Returns:
-
A raw FFI byte array containing data.
- std.requestStatus:value ()
-
Retrieve the current value of the request status
Returns:
-
A 32-bit integer as the status code.
- std.requestStatus:flags ()
-
Retrieve the current flags of the request status
Returns:
-
A 32-bit integer, which each bit as a flag.
Fields
- descriptor
-
Abstract class which allows the containment of data.
- pr The process where this descriptor lives on.
- addr The address of the descriptor in the process's memory.
- descriptor8
-
Detailed descriptor that is designed to hold 8-bit data.
This kind of descriptor usually used to hold 8-bit string or binary data, and can be coverted to string by using tostring.
- pr The process where this descriptor lives on.
- addr The address of the descriptor in the process's memory.
- descriptor16
-
Detailed descriptor that is designed to hold 16-bit data.
This kind of descriptor usually used to hold 16-bit Unicode string, and can be coverted to string by using tostring.
- pr The process where this descriptor lives on.
- addr The address of the descriptor in the process's memory.
- requestStatus
-
Struct holding the status of a request.
On EKA1, this struct simply holds an integer, which contains the result code of completed operation.
However, on EKA2, 32-bit
flagbitarray is also added to this struct to tell the status of the sync object associated with this request- pr The process where this request status lives on.
- addr The address of the request status in the process's memory.
