TinyCLog is mini C logging library. It is header only and thread safety.

Copy folder tiny_c_log
to your project directory.
#include "tiny_c_log/log_posix.h"
int main(void) {
LOG_DEBUG("this is a debug #%d", 1);
LOG_INFO("this is a info #%d", 2);
LOG_WARN("this is a warning #%d", 3);
LOG_ERROR("this is a error #%d", 4);
LOG_FATAL("this is a fatal #%d", 5);
return 0;
}
Since TinyCLog is header only, to avoid symbols redefined, all the definition of symbols with external linkage are wraped in #ifdef TINY_C_LOG_POSIX_IMPL
. So you have to make sure that macro TINY_C_LOG_POSIX_IMPL
is defined in one and only one compilation unit. USER_LOGFILE_LOCATION
and USER_LOG_LEVEL
are optional and are used to configure the location of log files and logging level.
