Logging with LogaxLogger¶
In a situation where callback is needed, no FILE* ability on the platform or the flags/options want to be shared across the log, the LogaxLogger struct can be used. No memory allocation is required when initaili
Iinitialized LogaxLogger¶
To iinitialized the LogaxLogger the function logax_init_logger can be used, it not necessary to call the logax_init_logger function, all it does is set the LogaxLogger flags to default value, output_stream to stdout and fill the empty callbacks with NULL, these can be self-managed.
#include <exotic/logax.h>
int main(int argc, char **argv) {
LogaxLogger logax_logger;
logax_init_logger(&logax_logger);
}
LogaxLogger Loggers¶
For each of the logging level in logax a function is provider that accepts LogaxLogger struct as parameter:
- logax_logger_trace
- logax_logger_debug
- logax_logger_info
- logax_logger_warn
- logax_logger_error
- logax_logger_fatal
Each of the function above invoke the corresponding logax_write_*_format_to_stream respectively, the default formatter when LogaxLogger is initialized with the function logax_init_logger is LOGAX_FORMATTER_TEXT, the output format can be changed using the function logax_set_formatter.
#include <exotic/logax.h>
int main(int argc, char **argv) {
LogaxLogger logax_logger;
logax_init_logger(&logax_logger);
logax_set_formatter(&logax_logger, LOGAX_FORMATTER_TEXT);
logax_logger_trace(&logax_logger, "%s", "Logging the test for TRACE");
logax_logger_debug(&logax_logger, "%s", "Logging the test for DEBUG");
logax_logger_info(&logax_logger, "%s", "Logging the test for INFO");
logax_logger_warn(&logax_logger, "%s", "Logging the test for WARN");
logax_logger_error(&logax_logger, "%s", "Logging the test for ERROR");
logax_logger_fatal(&logax_logger, "%s", "Logging the test for FATAL");
}
