HRESULT Read(
long indexGroup,
long indexOffset,
long cbLen,
long* pcbRead,
byte* pData);
Parameters
|
indexGroup |
[in] A variable of the type long that holds the index group of the variable we want to read. |
|
indexOffset |
[in] A variable of the type long that holds the index offset of the variable we want to read. |
|
cbLen |
[in] Count of byte we want to read from the variable. |
|
pcbRead |
[out] Pointer to a variable the returns the count of bytes we really had read. |
|
pData |
[out, size_is(cbLen), length_is(*pcbRead)] A pointer to the first element of a byte array with the length cbLen of the data we want to read from a variable in a Ads device. |
