/* Public Interface - May be used in end-application: */
/* Function Prototypes: */
/** Function to retrieve a given descriptor's size and memory location from the given descriptor type value,
* index and language ID. This function MUST be overridden in the user application (added with full, identical
* prototype and name so that the library can call it to retrieve descriptor data.
*
* \param[in] wValue The type of the descriptor to retrieve in the upper byte, and the index in the
* lower byte (when more than one descriptor of the given type exists, such as the
* case of string descriptors). The type may be one of the standard types defined
* in the DescriptorTypes_t enum, or may be a class-specific descriptor type value.
* \param[in] wIndex The language ID of the string to return if the \c wValue type indicates
* \ref DTYPE_String, otherwise zero for standard descriptors, or as defined in a
* class-specific standards.
* \param[out] DescriptorAddress Pointer to the descriptor in memory. This should be set by the routine to
* the address of the descriptor.
* \param[out] MemoryAddressSpace A value from the \ref USB_DescriptorMemorySpaces_t enum to indicate the memory
* space in which the descriptor is stored. This parameter does not exist when one
* of the \c USE_*_DESCRIPTORS compile time options is used.
*
* \note By default, the library expects all descriptors to be located in flash memory via the \c PROGMEM attribute.
* If descriptors should be located in RAM or EEPROM instead (to speed up access in the case of RAM, or to
* allow the descriptors to be changed dynamically at runtime) either the \c USE_RAM_DESCRIPTORS or the
* \c USE_EEPROM_DESCRIPTORS tokens may be defined in the project makefile and passed to the compiler by the -D
* switch.
*
* \return Size in bytes of the descriptor if it exists, zero or \ref NO_DESCRIPTOR otherwise.
