It probably depends on how these are used as to what you want here, however, if
all of these are data coming from LCS then I’d suggest you want your LCB
handlers to take in Data and then use something like:
__safe foreign handler MCDataGetBytePtr(in pData as Data) returns Pointer binds
__safe foreign handler MCDataGetLength(in pData as Data) returns LCUIndex binds
public handler DoSomething(in pPK as Data)
if MCDataGetLength(pPK) is not 32 then
throw “PK not 32 bytes"
variable tPK as Pointer
put MCDataGetBytePtr(pPK) into tPK
