- * Conversion functions
- * ====================
- *
- * There are two main directions of conversion:
- * - `inTargetType(...)`: Create a wrapper whose lifetime depends on the
- * input. The wrapper has type `TargetType`.
- * - `toTargetType(...)`: Create a standalone object of type `TargetType` that
- * corresponds to the input. The lifetime of the output does not depend on the
- * lifetime of the input.
- * - `wrapIn(TargetType*, ...)`: Same as `inTargetType()`, but for `TargetType`
- * that cannot be copied and/or moved efficiently, or when there are multiple
- * output arguments.
- * - `convertTo(TargetType*, ...)`: Same as `toTargetType()`, but for
- * `TargetType` that cannot be copied and/or moved efficiently, or when there
- * are multiple output arguments.
- *
- * `wrapIn()` and `convertTo()` functions will take output arguments before
- * input arguments. Some of these functions might return a value to indicate
- * success or error.
- *

+ * - `toTargetType(...)`: Create a standalone object of type `TargetType` that
+ * corresponds to the input. The lifetime of the output does not depend on the
+ * lifetime of the input.
+ * - `wrapIn(TargetType*, ...)`: Same as `inTargetType()`, but for `TargetType`
+ * that cannot be copied and/or moved efficiently, or when there are multiple
+ * output arguments.
+ * - `convertTo(TargetType*, ...)`: Same as `toTargetType()`, but for
+ * `TargetType` that cannot be copied and/or moved efficiently, or when there
+ * are multiple output arguments.
+ *
+ * `wrapIn()` and `convertTo()` functions will take output arguments before
+ * input arguments. Some of these functions might return a value to indicate
+ * success or error.
+ *
+ * In converting or wrapping something as a Treble type that contains a
+ * `hidl_handle`, `native_handle_t*` will need to be created and returned as
+ * an additional output argument, hence only `wrapIn()` or `convertTo()` would
+ * be available. The caller must call `native_handle_delete()` to deallocate the
+ * returned native handle when it is no longer needed.
+ *
+ * For types that contain file descriptors, `inTargetType()` and `wrapAs()` do
+ * not perform duplication of file descriptors, while `toTargetType()` and
+ * `convertTo()` do.

+/**
+ * Conversion functions for types outside media
+ * ============================================
+ *
+ * Some objects in libui and libgui that were made to go through binder calls do
+ * not expose ways to read or write their fields to the public. To pass an
+ * object of this kind through the HIDL boundary, translation functions need to
+ * work around the access restriction by using the publicly available
+ * `flatten()` and `unflatten()` functions.
+ *
+ * All `flatten()` and `unflatten()` overloads follow the same convention as
+ * follows:
+ *
+ * status_t flatten(ObjectType const& object,
+ * [OtherType const& other, ...]
+ * void*& buffer, size_t& size,
+ * int*& fds, size_t& numFds)
+ *
+ * status_t unflatten(ObjectType* object,
+ * [OtherType* other, ...,]
+ * void*& buffer, size_t& size,
+ * int*& fds, size_t& numFds)
+ *
+ * The number of `other` parameters varies depending on the `ObjectType`. For
+ * example, in the process of unflattening an object that contains
+ * `hidl_handle`, `other` is needed to hold `native_handle_t` objects that will
+ * be created.
+ *
+ * The last four parameters always work the same way in all overloads of
+ * `flatten()` and `unflatten()`:
+ * - For `flatten()`, `buffer` is the pointer to the non-fd buffer to be filled,
+ * `size` is the size (in bytes) of the non-fd buffer pointed to by `buffer`,
+ * `fds` is the pointer to the fd buffer to be filled, and `numFds` is the
+ * size (in ints) of the fd buffer pointed to by `fds`.
+ * - For `unflatten()`, `buffer` is the pointer to the non-fd buffer to be read
+ * from, `size` is the size (in bytes) of the non-fd buffer pointed to by
+ * `buffer`, `fds` is the pointer to the fd buffer to be read from, and
+ * `numFds` is the size (in ints) of the fd buffer pointed to by `fds`.
+ * - After a successful call to `flatten()` or `unflatten()`, `buffer` and `fds`
+ * will be advanced, while `size` and `numFds` will be decreased to reflect
+ * how much storage/data of the two buffers (fd and non-fd) have been used.
+ * - After an unsuccessful call, the values of `buffer`, `size`, `fds` and
+ * `numFds` are invalid.
+ *
+ * The return value of a successful `flatten()` or `unflatten()` call will be
+ * `OK` (also aliased as `NO_ERROR`). Any other values indicate a failure.
+ *
+ * For each object type that supports flattening, there will be two accompanying
+ * functions: `getFlattenedSize()` and `getFdCount()`. `getFlattenedSize()` will
+ * return the size of the non-fd buffer that the object will need for
+ * flattening. `getFdCount()` will return the size of the fd buffer that the
+ * object will need for flattening.
+ *
+ * The set of these four functions, `getFlattenedSize()`, `getFdCount()`,
+ * `flatten()` and `unflatten()`, are similar to functions of the same name in
+ * the abstract class `Flattenable`. The only difference is that functions in
+ * this file are not member functions of the object type. For example, we write
+ *
+ * flatten(x, buffer, size, fds, numFds)
+ *
+ * instead of
+ *
+ * x.flatten(buffer, size, fds, numFds)
+ *
+ * because we cannot modify the type of `x`.
+ *
+ * There is one exception to the naming convention: `hidl_handle` that
+ * represents a fence. The four functions for this "Fence" type have the word
+ * "Fence" attched to their names because the object type, which is
+ * `hidl_handle`, does not carry the special meaning that the object itself can
+ * only contain zero or one file descriptor.

+ * lifetime of the input.

+ * that cannot be copied and/or moved efficiently, or when there are multiple
+ * output arguments.
+ * - `convertTo(TargetType*, ...)`: Same as `toTargetType()`, but for
+ * `TargetType` that cannot be copied and/or moved efficiently, or when there
+ * are multiple output arguments.
+ *
+ * `wrapIn()` and `convertTo()` functions will take output arguments before
+ * input arguments. Some of these functions might return a value to indicate
+ * success or error.
+ *
+ * In converting or wrapping something as a Treble type that contains a
+ * `hidl_handle`, `native_handle_t*` will need to be created and returned as
+ * an additional output argument, hence only `wrapIn()` or `convertTo()` would
+ * be available. The caller must call `native_handle_delete()` to deallocate the
+ * returned native handle when it is no longer needed.
+ *
+ * For types that contain file descriptors, `inTargetType()` and `wrapAs()` do
+ * not perform duplication of file descriptors, while `toTargetType()` and

+/**
+ * Conversion functions for types outside media
+ * ============================================
+ *
+ * Some objects in libui and libgui that were made to go through binder calls do
+ * not expose ways to read or write their fields to the public. To pass an
+ * object of this kind through the HIDL boundary, translation functions need to
+ * work around the access restriction by using the publicly available
+ * `flatten()` and `unflatten()` functions.
+ *
+ * All `flatten()` and `unflatten()` overloads follow the same convention as
+ * follows:
+ *
+ * status_t flatten(ObjectType const& object,
+ * [OtherType const& other, ...]
+ * void*& buffer, size_t& size,
+ * int*& fds, size_t& numFds)
+ *
+ * status_t unflatten(ObjectType* object,
+ * [OtherType* other, ...,]
+ * void*& buffer, size_t& size,
+ * int*& fds, size_t& numFds)
+ *
+ * The number of `other` parameters varies depending on the `ObjectType`. For
+ * example, in the process of unflattening an object that contains
+ * `hidl_handle`, `other` is needed to hold `native_handle_t` objects that will
+ * be created.
+ *
+ * The last four parameters always work the same way in all overloads of
+ * `flatten()` and `unflatten()`:
+ * - For `flatten()`, `buffer` is the pointer to the non-fd buffer to be filled,
+ * `size` is the size (in bytes) of the non-fd buffer pointed to by `buffer`,
+ * `fds` is the pointer to the fd buffer to be filled, and `numFds` is the
+ * size (in ints) of the fd buffer pointed to by `fds`.
+ * - For `unflatten()`, `buffer` is the pointer to the non-fd buffer to be read
+ * from, `size` is the size (in bytes) of the non-fd buffer pointed to by
+ * `buffer`, `fds` is the pointer to the fd buffer to be read from, and
+ * `numFds` is the size (in ints) of the fd buffer pointed to by `fds`.
+ * - After a successful call to `flatten()` or `unflatten()`, `buffer` and `fds`
+ * will be advanced, while `size` and `numFds` will be decreased to reflect
+ * how much storage/data of the two buffers (fd and non-fd) have been used.
+ * - After an unsuccessful call, the values of `buffer`, `size`, `fds` and
+ * `numFds` are invalid.
+ *
+ * The return value of a successful `flatten()` or `unflatten()` call will be
+ * `OK` (also aliased as `NO_ERROR`). Any other values indicate a failure.
+ *
+ * For each object type that supports flattening, there will be two accompanying
+ * functions: `getFlattenedSize()` and `getFdCount()`. `getFlattenedSize()` will
+ * return the size of the non-fd buffer that the object will need for
+ * flattening. `getFdCount()` will return the size of the fd buffer that the
+ * object will need for flattening.
+ *
+ * The set of these four functions, `getFlattenedSize()`, `getFdCount()`,
+ * `flatten()` and `unflatten()`, are similar to functions of the same name in
+ * the abstract class `Flattenable`. The only difference is that functions in
+ * this file are not member functions of the object type. For example, we write
+ *
+ * flatten(x, buffer, size, fds, numFds)
+ *
+ * instead of
+ *
+ * x.flatten(buffer, size, fds, numFds)
+ *
+ * because we cannot modify the type of `x`.
+ *
+ * There is one exception to the naming convention: `hidl_handle` that
+ * represents a fence. The four functions for this "Fence" type have the word
+ * "Fence" attched to their names because the object type, which is
+ * `hidl_handle`, does not carry the special meaning that the object itself can
+ * only contain zero or one file descriptor.
