- /** Function to retrieve a given descriptor's size and memory location from the given descriptor type value,\r
- * index and language ID. This function MUST be overridden in the user application (added with full, identical \r
- * prototype and name except for the \ref ATTR_WEAK attribute) so that the library can call it to retrieve descriptor \r
- * data.\r
- *\r
- * \param wValue The type of the descriptor to retrieve in the upper byte, and the index in the \r
- * lower byte (when more than one descriptor of the given type exists, such as the\r
- * case of string descriptors). The type may be one of the standard types defined\r
- * in the DescriptorTypes_t enum, or may be a class-specific descriptor type value.\r
- * \param wIndex The language ID of the string to return if the wValue type indicates DTYPE_String,\r
- * otherwise zero for standard descriptors, or as defined in a class-specific\r
- * standards.\r
- * \param DescriptorAddress Pointer to the descriptor in memory. This should be set by the routine to\r
- * the address of the descriptor.\r
- *\r
- * \note By default, the library expects all descriptors to be located in flash memory via the PROGMEM attribute.\r
- * If descriptors should be located in RAM or EEPROM instead (to speed up access in the case of RAM, or to\r
- * allow the descriptors to be changed dynamically at runtime) either the USE_RAM_DESCRIPTORS or the \r
- * USE_EEPROM_DESCRIPTORS tokens may be defined in the project makefile and passed to the compiler by the -D\r
- * switch.\r
- *\r
- * \return Size in bytes of the descriptor if it exists, zero or \ref NO_DESCRIPTOR otherwise\r
