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. |
|
cbRdLen |
[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. |
|
pRdData |
[out, size_is(cbRdLen), length_is(*pcbRead)] A pointer to the first element of a byte array with the length cbRdLen of the data we want to read from a variable in an Ads device. |
|
cbWrLen |
[in] Count of byte we want to write to the variable. |
|
pWrData |
[in, size_is(pWrData)] A pointer to the first element of a byte array with the length cbWrLen of the data we want to write to a variable in an Ads device. |
