Porting Tutorials

This topic describes how to port some C applications to the Symbian platform.

It uses Hello , ConsoleApp and GUIApp examples . The first two are simple console-based examples. The third is a command-line driven program which has been converted into a standard Symbian application. It also describes typical problems which may be encountered when porting C code to the Symbian platform, including the restriction on writeable data in DLLs. These example codes can be found in directory examples\stdlib\ .

NOTE : These examples may not be present on all Symbian platform SDKs.

Some of the code for the second two examples was taken from the FreeBSD source code. For information on FreeBSD, see http://www.freebsd.org .
