* Here is an example:
*
- * @code
- * #include <stdlib.h>
- * #include <stdio.h>
- *
- * #include <Eina.h>
- *
- * void test(int i)
- * {
- * EINA_LOG_DBG("Entering test");
- *
- * if (i < 0)
- * {
- * EINA_LOG_ERR("Argument is negative");
- * return;
- * }
- *
- * EINA_LOG_INFO("argument non negative");
- *
- * EINA_LOG_DBG("Exiting test");
- * }
- *
- * int main(void)
- * {
- * if (!eina_init())
- * {
- * printf("log during the initialization of Eina_Log module\n");
- * return EXIT_FAILURE;
- * }
- *
- * test(-1);
- * test(0);
- *
- * eina_shutdown();
- *
- * return EXIT_SUCCESS;
- * }
- * @endcode
+ * @include eina_log_02.c
*
* If you compiled Eina without debug mode, execution will yield only one log
* message, which is "argument is negative".
* expects a list in the form domain_name1:level1,domain_name2:level2,... . For
* example:
*
- * @code
- *
- * EINA_LOG_LEVELS=mymodule1:5,mymodule2:2,mymodule3:0 ./myapp
- *
- * @endcode
+ * @verbatim EINA_LOG_LEVELS=mymodule1:5,mymodule2:2,mymodule3:0 ./myapp@endverbatim
*
* This line would set mymodule1 level to 5, mymodule2 level to 2 and mymodule3
* level to 0.
*
- *
* There's also a global logger to which EINA_LOG_(ERR, DBG, INFO, CRIT, WARN)
* macros do log on. It is a logger that is created internally by Eina Log with
* an empty name and can be used for general logging (where logging domains do
* This variable specifies the level of the global logging domain and the level
* of domains that haven't been set through EINA_LOG_LEVELS. Here's an example:
*
- * @code
- *
- * EINA_LOG_LEVEL=3 EINA_LOG_LEVELS=module1:10,module3:2 ./myapp
- *
- * @endcode
+ * @verbatim EINA_LOG_LEVEL=3 EINA_LOG_LEVELS=module1:10,module3:2 ./myapp@endverbatim
*
* Supposing you have modules named "module1", "module2" and "module3", this
* line would result in module1 with level 10, module2 with level 3 and module3
* The global level (EINA_LOG_LEVEL) can also be set through code, using
* eina_log_level_set() function.
*
- *
* While developing your libraries or applications, you may notice that
* EINA_LOG_DOM_(ERR, DBG, INFO, CRIT, WARN) macros also print out
* messages from eina itself. Here we introduce another environment variable
* see your own domain's messages easier without having to sift through a lot of
* internal eina debug messages. Here's an example:
*
- * @code
- *
- * EINA_LOG_LEVEL=3 EINA_LOG_LEVELS_GLOB=eina_*:0 ./myapp
- *
- * @endcode
+ * @verbatim EINA_LOG_LEVEL=3 EINA_LOG_LEVELS_GLOB=eina_*:0 ./myapp@endverbatim
*
* This will disable eina_log output from all internal eina code thus allowing
* you to see your own domain messages easier.
* Here is an example of custom callback, whose behavior can be
* changed at runtime:
*
- * @code
- * #include <stdlib.h>
- * #include <stdio.h>
- *
- * #include <eina_log.h>
- *
- * #define log(fmt, ...) \
- * eina_log_print(EINA_LOG_LEVEL_ERR, __FILE__, __FUNCTION__, __LINE__, fmt, ##__VA_ARGS__)
- *
- * typedef struct _Data Data;
- *
- * struct _Data
- * {
- * int to_stderr;
- * };
- *
- * void print_cb(const Eina_Log_Domain *domain,
- * Eina_Log_Level level,
- * const char *file,
- * const char *fnc,
- * int line,
- * const char *fmt,
- * void *data,
- * va_list args)
- * {
- * Data *d;
- * FILE *output;
- * char *str;
- *
- * d = (Data *)data;
- * if (d->to_stderr)
- * {
- * output = stderr;
- * str = "stderr";
- * }
- * else
- * {
- * output = stdout;
- * str = "stdout";
- * }
- *
- * fprintf(output, "%s:%s:%s (%d) %s: ",
- * domain->domain_str, file, fnc, line, str);
- * vfprintf(output, fmt, args);
- * putc('\n', output);
- * }
- *
- * void test(Data *data, int i)
- * {
- * if (i < 0)
- * data->to_stderr = 0;
- * else
- * data->to_stderr = 1;
- *
- * log("log message...");
- * }
- *
- * int main(void)
- * {
- * Data data;

- * if (!eina_init())
- * {
- * printf("log during the initialization of Eina_Log module\n");
- * return EXIT_FAILURE;
- * }
- *
- * eina_log_print_cb_set(print_cb, &data);
- *
- * test(&data, -1);
- * test(&data, 0);
- *
- * eina_shutdown();
- *
- * return EXIT_SUCCESS;

- * @code
- * #include <stdlib.h>
- * #include <stdio.h>
- *
- * #include <eina_log.h>
- *
- * void test_warn(void)

- * test_warn();
- *
- * eina_shutdown();
- *
- * return EXIT_SUCCESS;
- * }
- * @endcode
+ * @include eina_log_01.c
*
* Compile this code with the following command:
*
- * @code
- * gcc -Wall -o test_Eina_Log test_eina.c `pkg-config --cflags --libs eina`
- * @endcode
+ * @verbatim gcc -Wall -o eina_log_01 eina_log_01.c `pkg-config --cflags --libs eina`@endverbatim
*
* Now execute the program with:
*
- * @code
- * EINA_LOG_LEVEL=2 ./test_eina_log
- * @endcode
+ * @verbatim EINA_LOG_LEVEL=2 ./eina_log_01@endverbatim
*
