Expand description
Interface for developing and debugging drivers. This interface should only be used for development and disabled in release builds.
Variants§
GetDriverInfo
Returns a list of all drivers that are known to the system. If a |driver_filter| is provided, the returned list will be filtered to only include drivers specified in the filter.
|iterator| is closed with following epitaphs on error: ZX_ERR_NOT_FOUND indicates that there is no driver matching the given path for at least one driver in |driver_filter|. ZX_ERR_BUFFER_TOO_SMALL indicates that the driver’s bind program is longer than the maximum number of instructions (BIND_PROGRAM_INSTRUCTIONS_MAX).
GetCompositeNodeSpecs
Fields
iterator: ServerEnd<CompositeNodeSpecIteratorMarker>
control_handle: DriverIndexControlHandle
Returns a list of all composite node specs that are known to the system. If a |name_filter| is provided, the returned list will only include 1 spec, the one with that exact name.
|iterator| is closed with following epitaphs on error: ZX_ERR_NOT_FOUND indicates that there are no specs or if a |name_filter| is provided, that there are no specs with that name.
