<p>The length of the low-level environment description parameter. The minimum

length is 8. If the length is larger than the size of the receiver variable,
|

|
the results are not predictable. The API returns as much information as it can
|
||
|
|
fit in this length. It the available information is longer, it is truncated. If
|

|
|
the available information is shorter, the unused output is unchanged; whatever
|
||
|
|
is already stored in that space remains there. To determine how much
|
||
|
|
information the API actually returns in response to this call, see the bytes
|
||
|
|
returned field. To determine how much information the API could return if space
|
||

|
were available, see the bytes available field.</p>
