\membersection{wxDatagramSocket::wxDatagramSocket}\label{wxdatagramsocketctor}

\func{}{wxDatagramSocket}{\param{wxSocketFlags}{ flags = wxSOCKET\_NONE}}

Constructor.

\wxheading{Parameters}

\docparam{flags}{Socket flags (See \helpref{wxSocketBase::SetFlags}{wxsocketbasesetflags})}

\membersection{wxDatagramSocket::\destruct{wxDatagramSocket}}\label{wxdatagramsocketdtor}

\func{}{\destruct{wxDatagramSocket}}{\void}

Destructor. Please see \helpref{wxSocketBase::Destroy}{wxsocketbasedestroy}.

\membersection{wxDatagramSocket::ReceiveFrom}\label{wxdatagramsocketreceivefrom}

\func{wxDatagramSocket\&}{ReceiveFrom}{\param{wxSockAddress\&}{ address}, \param{void *}{ buffer}, \param{wxUint32}{ nbytes}}

This function reads a buffer of {\it nbytes} bytes from the socket.

Use \helpref{LastCount}{wxsocketbaselastcount} to verify the number of bytes actually read.

Use \helpref{Error}{wxsocketbaseerror} to determine if the operation succeeded.

\wxheading{Parameters}

\docparam{address}{Any address - will be overwritten with the address of the peer that sent that data.}

\docparam{buffer}{Buffer where to put read data.}

\docparam{nbytes}{Number of bytes.}

\wxheading{Return value}

Returns a reference to the current object, and the address of the peer that sent the data on address param.

\membersection{wxDatagramSocket::SendTo}\label{wxdatagramsocketsendto}

\func{wxDatagramSocket\&}{SendTo}{\param{const wxSockAddress\&}{ address}, \param{const void *}{ buffer}, \param{wxUint32}{ nbytes}}

This function writes a buffer of {\it nbytes} bytes to the socket.

Use \helpref{LastCount}{wxsocketbaselastcount} to verify the number of bytes actually wrote.

Use \helpref{Error}{wxsocketbaseerror} to determine if the operation succeeded.

\wxheading{Parameters}

\docparam{address}{The address of the destination peer for this data.}

\docparam{buffer}{Buffer where read data is.}

\docparam{nbytes}{Number of bytes.}

\wxheading{Return value}

Returns a reference to the current object.
