Reads a resource into a heap descriptor, returns a pointer to that descriptor and pushes the pointer onto the cleanup stack.

A heap descriptor of appropriate length is allocated for the resource. Ownership of the heap descriptor passes to the caller who must destroy it and pop its pointer off the cleanup stack when it is no longer needed.The search for the resource uses the following algorithm:A resource id in the range 1 to 4095 is looked up in this resource file. The function leaves if there is no matching resource.If the resource id is greater than 4095, then the most significant 20 bits of the resource id is treated as an offset and the least significant 12 bits is treated as the real resource id. If the offset matches the offset value defined for this file, then the resource is looked up in this resource file using the real resource id (i.e. the least significant 12 bits). If the offset does not match, then the function leaves.Note, do not call this function until a call to ConfirmSignatureL() has completed successfully.

The method will decomress the unicode data (aCompressedUnicode argument) and append the decompressed data to the end of aBuffer (aBuffer argument).

Closes the resource file reader. This function is called after finishing reading all resources.

Initialises the offset value from the first resource.

The function tests to catch cases where the first resource is not an RSS_SIGNATURE. It assumes that the first resource in the file consists of two 32-bit integers. The first integer contains the version number and the second is a self-referencing link whose value is the offset for the resources in the file, plus 1.This function must be called before calling Offset() , AllocReadL(), AllocReadLC() or ReadL() .

The method will decompress the unicode data (aInputResourceData argument), allocate enough memory from the heap for the decompressed data, copy the data there and return a descriptor to the decompressed data.

The method doesn't own the allocated heap memory for the decompressed data. It's a caller responsibility to deallocate the allocated memory.

Returns the offset value defined for this resource file.

This function must not be called until a call to ConfirmSignatureL() has completed successfully, otherwise the value returned by this function may be meaningless.

Tests whether the resource file owns the specified resource id.

The resource file owns the resource id if the most significant 20 bits of the resource id are zero or match the offset value as returned from a call to the Offset() member function or if the resource id is not out of range.

Retrieve the UID tuple of the opened resource file.
