This routine returns a list of valid values for a given parameter name
|
|
for a given card.
|
|
|
|
Arguments:
|
|
|
|
lNetcardId - The Id of the card desired.
|
|
|
|
pwchParam - A WCHAR string of the parameter name to query the values of.
|
|
|
|
plValues - A pointer to a list of LONGs into which we store valid values
|
|
for the parameter.
|
|
|
|
plBuffSize - At entry, the length of plValues in LONGs. At exit, the
|
|
number of LONGs stored in plValues.
|
|
|
|
Return Value:
|
|
|
|
0 if nothing went wrong, else the appropriate WINERROR.H value.

Routine Description:
|
|
|
|
Returns a localized, displayable name for a specific parameter. All the
|
|
parameters that this file uses are define by MS, so no strings are
|
|
needed here.
|
|
|
|
Arguments:
|
|
|
|
pwchParam - The parameter to be queried.
|
|
|
|
pwchBuffer - The buffer to store the result into.
|
|
|
|
cwchBufferSize - The length of pwchBuffer in WCHARs.
|
|
|
|
Return Value:
|
|
|
|
ERROR_INVALID_PARAMETER -- To indicate that the MS supplied strings
|
|
should be used.
