| Language | Syntax |
|---|---|
| C | HRESULT IltmmMemory_getData(pMem, Index, Count, pVal) |
| C++ | HRESULT GetData(Index, Count, pVal) |
Pointer to an IltmmMemory interface.
Index, or offset, from which to retrieve the data from the objects buffer.
Size of the data to retrieve (number of elements, in bytes).
Pointer to a variable to be updated with a VARIANT containing a SAFEARRAY reference to the block of data.
| Value | Meaning |
|---|---|
| S_OK | The function was successful. |
| <> S_OK | An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation. |
If the size of the data to retrieve is larger than the size available after the offset, the function will retrieve only the available data between the offset and the end of the buffer.
This function allocates the required memory for the SAFEARRAY; the caller is responsible for freeing it.
The area of the object's buffer from which the data is retrieved will be locked for the duration of the call.
Win32, x64.
