class EndpointList
Defined at line 311 of file ../../src/devices/usb/lib/usb/include/usb/usb.h
EndpointList is used to iterate all of the USB endpoint descriptors of an Interface. It is
created by calling GetEndpointList on an Interface. The returned descriptor pointers are valid
for the lifetime of the InterfaceList used to create the parent Interface. EndpointList
implements a standard C++ iterator interface that returns Endpoint.
Example Usage:
std::optional
<InterfaceList
> interfaces;
status = InterfaceList::Create(my_client, true,
&interfaces
);
if (status != ZX_OK) {
...
}
// Find the first interrupt endpoint and copy it for use by the driver.
for (const auto
&
interface : *interfaces) {
for (auto
&
endpoint : interface.GetEndpointList()) {
if (usb_ep_direction(endpoint.descriptor()) == EndpointDirection::kIn
&
&
usb_ep_type(endpoint.descriptor()) ==
EndpointType::kInterrupt) {
return std::make_optional
<usb
_endpoint_descriptor_t>(*endpoint.descriptor());
}
}
}
