Definition: BasicTypes.h:51
C++-compatible configuration header for fprime configuration.
Helper base-class for setting up Berkeley sockets.
Definition: IpSocket.hpp:47
SocketIpStatus send(const U8 *const data, const U32 size)
send data out the IP socket from the given buffer
Definition: IpSocket.cpp:168
SocketIpStatus configure(const char *hostname, const U16 port, const U32 send_timeout_seconds, const U32 send_timeout_microseconds)

Status associated with the received data.
@ RECV_OK
Receive worked as expected.
@ RECV_ERROR
Receive error occurred retrying may succeed.
Status returned by the send call.
@ SEND_ERROR
Send error occurred retrying may succeed.
@ SEND_RETRY
Data send should be retried.
@ SEND_OK
Send worked as expected.
