This sample demonstrates Using the low level ICU data handling interfaces (udata) to create and later access user data.

Files: writer.c C source for Writer application, will generate data file to be read by Reader. reader.c C source for Reader application, will read file created by Writer udata.sln Windows MSVC workspace. Double-click this to get started. udata.vcproj Windows MSVC project file

To Build udata on Windows 1. Install and build ICU 2. In MSVC, open the workspace file icu\samples\udata\udata.sln 3. Choose a Debug or Release build. 4. Build.

To Run on Windows 1. Start a command shell window 2. Add ICU's bin directory to the path, e.g. set PATH=c:\icu\bin;%PATH% (Use the path to where ever ICU is on your system.) 3. cd into the udata directory, e.g. cd c:\icu\source\samples\udata\debug 4. Run it writer reader IMPORTANT: On some systems, the reader and writer executables may not be in the same directory. If this is the case, this will likely cause a problem with reader looking for the .dat file in the wrong directory).

To Build on Unixes 1. Build ICU.
Specify an ICU install directory when running configure, using the --prefix option. The steps to build ICU will look something like this: cd /source runConfigureICU --prefix [other options] gmake all

2.  Install ICU, 
       gmake install

3.  Compile
       You will need to set ICU_PATH to the location of your ICU source tree, for example ICU_PATH=/home/srl/icu   (containing source, etc.)
       cd <icu directory>/source/samples/udata
       gmake ICU_PATH=<icu source directory> ICU_PREFIX=<icu install directory)

To Run on Unixes cd /source/samples/udata gmake ICU_PREFIX= check -or-

       export LD_LIBRARY_PATH=<icu install directory>/lib:.:$LD_LIBRARY_PATH
       writer
       reader

Note: The name of the LD_LIBRARY_PATH variable is different on some systems. If in doubt, run the sample using "gmake check", and note the name of the variable that is used there. LD_LIBRARY_PATH is the correct name for Linux and Solaris.
