Header & | header () |
Returns a reference to the header. | |
std::vector< uint8_t > & | data () |
Returns a reference to the byte vector containing data. | |
std::vector< SharedFD > & | fds () |
Returns a reference to the vector containing file descriptors. | |
const Header & | header () const |
Returns a const reference to the header. | |
const std::vector< uint8_t > & | data () const |
Returns a const reference to the byte vector containing data. | |

libcamera::IPCMessage::IPCMessage | ( | uint32_t | cmd | ) |
Construct an IPCMessage instance with a given command code.
[in] | cmd | The command code |
libcamera::IPCMessage::IPCMessage | ( | const Header & | header | ) |
Construct an IPCMessage instance with a given header.
[in] | header | The header that the constructed IPCMessage will contain |
libcamera::IPCMessage::IPCMessage | ( | IPCUnixSocket::Payload & | payload | ) |
Construct an IPCMessage instance from an IPC payload.
[in] | payload | The IPCUnixSocket payload to construct from |
This essentially converts an IPCUnixSocket payload into an IPCMessage. The header is extracted from the payload into the IPCMessage's header field.
If the IPCUnixSocket payload had any valid file descriptors, then they will all be invalidated.
IPCUnixSocket::Payload libcamera::IPCMessage::payload | ( | ) | const |
Create an IPCUnixSocket payload from the IPCMessage.
This essentially converts the IPCMessage into an IPCUnixSocket payload.
