Routine Description:
Changes printer attributes by validating sharing information. Already the validated attributes are set, we want to validate by changing the share information
Arguments:
dNewAttributes - New attributes specified on SetPrinter call
dOldAttributes - pIniPrinter->Attributes before the call
pIniPrinter - of the printer we are changing attributes
pIniSpooler - Spooler that owns printer
pszNewShareName - the share name that will be set if SetPrinter succeeds
bShareRecreate - Share must be recreated because the printer or share name changed.
bShareUpdate - Share just needs to be updated, since comment / SD changed.
Return Value:
DWORD TRUE on success, FALSE else.
