Detailed Description

Platform handle for the DRM platform.

An RPlatformHandle implementation (see RPlatformHandle) whose platform() is RPlatform::DRM. It holds the set of DRM device file descriptors a client is allowed to use.

Use Make() to create an instance.

Constructor & Destructor Documentation

◆ ~RDRMPlatformHandle()

~RDRMPlatformHandle ( )

noexcept

Closes all internally duplicated DRM file descriptors.

Member Function Documentation

◆ Make()

static std::shared_ptr< RDRMPlatformHandle > Make ( const std::unordered_set< RDRMFdHandle > & fds )

staticnoexcept

Creates a DRM platform handle from a set of DRM device file descriptors.

Each file descriptor is duplicated internally (with F_DUPFD_CLOEXEC), so the caller retains ownership of the passed descriptors. Handles that fail to duplicate are skipped.

Parameters

fds	A non-empty set of DRM file descriptors (with associated user data).

Returns: A shared pointer to the created handle, or nullptr if fds is empty or none of the descriptors could be duplicated.

◆ fds()

const std::unordered_set< RDRMFdHandle > & fds ( ) const

inlinenoexcept

Returns the set of internally duplicated DRM file descriptors.
