You should not have to include any network header files other than <TTCLASS="FILENAME">gnet/gnet.h</TT>. </P><P> GLib includes the functions <TTCLASS="FUNCTION">g_ntohs</TT>, <TTCLASS="FUNCTION">g_htons</TT>, <TTCLASS="FUNCTION">g_ntohl</TT>, and <TTCLASS="FUNCTION">g_htonl</TT>. Use these instead of the versions in <TTCLASS="FILENAME">netinet/in.h</TT>. </P><P> "Non-blocking" functions return immediately. Asynchronous functions are non-blocking and call a callback when completed. IO operations on socket IOChannels (e.g., read, write) are not non-blocking. Use GLib's asynchronous g_io_add_watch on a GIOChannel to set a callback to be called when the GIOChannel can be read (or written to, or there's an error). See the echoclient and echoserver for examples. </P></DIV><DIVCLASS="NAVFOOTER"><BRCLEAR="all"><BR><TABLEWIDTH="100%"BORDER="0"BGCOLOR="#000000"CELLPADDING="1"CELLSPACING="0"><TR><TDWIDTH="25%"BGCOLOR="#C00000"ALIGN="left"><AHREF="gnet-developers.html"><FONTCOLOR="#FFFFFF"SIZE="3"><B><<< Previous Page</B></FONT></A></TD><TDWIDTH="25%"BGCOLOR="#0000C0"ALIGN="center"><FONTCOLOR="#FFFFFF"SIZE="3"><B><AHREF="book1.html"><FONTCOLOR="#FFFFFF"SIZE="3"><B>Home</B></FONT></A></B></FONT></TD><TDWIDTH="25%"BGCOLOR="#00C000"ALIGN="center"><FONTCOLOR="#FFFFFF"SIZE="3"><B><AHREF="gnet-developers.html"><FONTCOLOR="#FFFFFF"SIZE="3"><B>Up</B></FONT></A></B></FONT></TD><TDWIDTH="25%"BGCOLOR="#C00000"ALIGN="right"><AHREF="gnet-examples.html"><FONTCOLOR="#FFFFFF"SIZE="3"><B>Next Page >>></B></FONT></A></TD></TR><TR><TDCOLSPAN="2"ALIGN="left"><FONTCOLOR="#FFFFFF"SIZE="3"><B>GNet for developers</B></FONT></TD><TDCOLSPAN="2"ALIGN="right"><FONTCOLOR="#FFFFFF"SIZE="3"><B>GNet Examples</B></FONT></TD></TR></TABLE></DIV></BODY></HTML>⌨️ 快捷键说明
