TransactParcel is used by 1.0.0 official user-processes, while starting with ~~{unknown version}~~ TransactParcelAuto is used instead.

TransactParcel is used by 1.0.0 official user-processes, while starting with 3.0.0 TransactParcelAuto is used instead.

For IHOSBinderDriver, the below '''ID''' is loaded from the layer's [[Display_services#NativeWindow]].

== TransactParcel ==

Takes a s32 (~~Binder~~ ID?), an u32 ('''code'''), a type-0x5 input buffer ('''parcel_data'''), a type-0x6 output buffer ('''parcel_reply''') and an input u32 ('''flags'''). Each word is placed immediately after the previous word.

Takes a s32 ('''ID'''), an u32 ('''code'''), a type-0x5 input buffer ('''parcel_data'''), a type-0x6 output buffer ('''parcel_reply''') and an input u32 ('''flags'''). Each word is placed immediately after the previous word.

Analogous to "onTransact" from "android.os.IServiceManager".

== AdjustRefcount ==

Takes 3 input s32s: ~~{Binder~~ ID?}, '''addval''', and '''type'''. Each word immediately follows the previous word. No additional output.

Takes 3 input s32s: '''ID''', '''addval''', and '''type'''. Each word immediately follows the previous word. No additional output.

'''type''' indicates whether the strong reference count or weak reference count will be affected. 0 indicates the weak reference count, while 1 indicates the strong reference count.

== GetNativeHandle ==

Takes an input s32 and u32, with the latter immediately following the previous word. Returns an output event handle.

Takes an input s32 ('''ID''') and u32, with the latter immediately following the previous word. Returns an output event handle.

== TransactParcelAuto ==

Takes a s32 (~~Binder~~ ID?), an u32 ('''code'''), a type-0x21 input buffer ('''parcel_data'''), a type-0x22 output buffer ('''parcel_reply''') and an input u32 ('''flags'''). Each word is placed immediately after the previous word.
