* @file msgs_i18n.c
* @brief example for how to use translate libmicrohttpd messages
* @author Christian Grothoff, Silvio Clecio (silvioprog)
*/
/*
* suposing you are in the libmicrohttp root directory and the LANG is `pt_BR`: *
*
* # generate the POT file
* $ xgettext --keyword=_ --language=C --add-comments --sort-output -o libmicrohttpd.pot src/microhttpd/*.c
*
* # generate the PO file
* $ msginit --input=libmicrohttpd.pot --locale=pt_BR --output=libmicrohttpd.po
*
* # open the generated .po in any program like Poedit and translate the MHD messages; once done, let's go to the test:
* mkdir -p src/examples/locale/pt_BR/LC_MESSAGES
* mv libmicrohttpd.mo libmicrohttpd.po src/examples/locale/pt_BR/LC_MESSAGES
* cd src/examples/
* gcc -o msgs_i18n msgs_i18n.c -lmicrohttpd
* export LANGUAGE=pt_BR
* ./msgs_i18n
* # it may print: Opção inválida 4196490! (Você terminou a lista com MHD_OPTION_END?)
*
* # tip: if you get any problem in your i18n application, you can debug it using `strace` tool, e.g:
* $ strace -e trace=open ./msgs_i18n
*
* That's all!
