## cl.resourceManager.1 Change in the Meaning of the Return Value for the API Used to Obtain the rawfile Descriptor
Changed the meaning of the return value for the API used to obtain the rawfile descriptor after the non-decompression feature is added in this version. The change in the meaning of the return value, namely, **descriptor: RawFileDescriptor {fd, offset, length}**, is described as follows:
**Before change:**
**fd**: file descriptor for accessing the rawfile.
**offset**: offset for accessing the rawfile. In this case, the value is **0**.
**length**: size of the rawfile to access.
**After change:**
**fd**: file descriptor for accessing the HAP where the rawfile is located.
**offset**: offset of the accessed rawfile relative to the HAP.
**length**: size of the rawfile to access.
**Change Impact**
In versions earlier than 4.0.2.2, the rawfile can be accessed only through **fd**. In version 4.0.2.2 or later, the rawfile can be accessed only through **{fd, offset, and length}**.
In versions earlier than 4.0.6.2, only the values of string resources can be directly obtained. In 4.0.6.2 or later, the values of string resources can be formatted based on the input arguments for enhanced query.
The following error codes are added:
9001007 If the resource obtained by resId formatting error.
9001008 If the resource obtained by resName formatting error.
**Sample Code**
The following uses **getStringSync** as an example. Before the change, only example 1 is supported. After the change, both example 1 and example 2 are supported.
