Function RTUEnumDescriptors

RTUEnumDescriptors searches arbitrary descriptors within a configuration:

const void * RTUEnumDescriptors(const RTUConfigurationDescriptor * Config, 
                                int MinDescriptorType, 
                                int Index);

Parameters

Config

Configuration within which to search.

MinDescriptorType

Minimal descriptor type to return. Standard descriptors have low values in the range 1..8 (see type RTUDescriptorType in Rtusb.h). Class-specific descriptors have larger values.

Index

Zero-based index of matching descriptor to return.

return value

If a descriptor is found, a pointer to it is returned, NULL otherwise.

This function can be used to browse class- or device-specific descriptors. To locate a specific descriptor type, use RTUGetDescriptor.
