RegistryEntryPropertyMod

RegistryEntryPropertyMod searches for name entries that have a property with a specified modifier.



 
OSStatus RegistryEntryPropertyMod (

                     RegEntryIter *cookie,

                     RegEntryIterationOp relationship,

                     RegEntryID *foundEntry,

                     Boolean *done,

                     RegEntryModifiers matchingModifiers);

--> cookie: Pointer to the iterator returned by the RegistryIterateCreate function for the name entry iterate and search routines.
--> relationship: The search relationship (values defined in Data Structures and Constants).
<-- foundEntry: Pointer to the ID of the next name entry found.
<-- done: Pointer, contains a value of true when searching is completed.
--> matchingModifiers: Pointer to the modifiers to be matched.

DESCRIPTION

RegistryEntryPropertyMod searches for name entries, using the relation indicated by relationship, that have a property with a specified modifier. It returns the RegEntryID value that identifies the next name entry found in foundEntry, or true in done if all entries have been exhausted.

RegistryEntryPropertyMod returns only name entries with properties that have modifiers that match the value of matchingModifiers. It uses a bit AND operation to determine when the bits set in matchingModifiers are also set in the property.
