ioctl CEC_ADAP_G_CAPS &manvol; CEC_ADAP_G_CAPS Query device capabilities int ioctl int fd int request struct cec_caps *argp fd File descriptor returned by open(). request CEC_ADAP_G_CAPS argp Note: this documents the proposed CEC API. This API is not yet finalized and is currently only available as a staging kernel module. All cec devices must support the CEC_ADAP_G_CAPS ioctl. To query device information, applications call the ioctl with a pointer to a &cec-caps;. The driver fills the structure and returns the information to the application. The ioctl never fails. &cs-str; char driver[32] The name of the cec adapter driver. char name[32] The name of this CEC adapter. The combination driver and name must be unique. __u32 capabilities The capabilities of the CEC adapter, see . __u32 version CEC Framework API version, formatted with the KERNEL_VERSION() macro. &cs-def; CEC_CAP_PHYS_ADDR 0x00000001 Userspace has to configure the physical address by calling &CEC-ADAP-S-PHYS-ADDR;. If this capability isn't set, then setting the physical address is handled by the kernel whenever the EDID is set (for an HDMI receiver) or read (for an HDMI transmitter). CEC_CAP_LOG_ADDRS 0x00000002 Userspace has to configure the logical addresses by calling &CEC-ADAP-S-LOG-ADDRS;. If this capability isn't set, then the kernel will have configured this. CEC_CAP_TRANSMIT 0x00000004 Userspace can transmit CEC messages by calling &CEC-TRANSMIT;. This implies that userspace can be a follower as well, since being able to transmit messages is a prerequisite of becoming a follower. If this capability isn't set, then the kernel will handle all CEC transmits and process all CEC messages it receives. CEC_CAP_PASSTHROUGH 0x00000008 Userspace can use the passthrough mode by calling &CEC-S-MODE;. CEC_CAP_RC 0x00000010 This adapter supports the remote control protocol. CEC_CAP_MONITOR_ALL 0x00000020 The CEC hardware can monitor all messages, not just directed and broadcast messages. &return-value;
