Name
tplog — Print log message to current logger
Synopsis
#include <ndebug.h>
void tplog(int lev, char *message);
or
#define TP_LOG(lev, fmt, …)
Link with -lnstd -lpthread -lrt -lm
DESCRIPTION
Function writes the message to current log file. lev is logging level. For function version log message goes as message parameter. For C/C++ coding it is recommended to use macro version TP_LOG, as it have a format string and it uses more efficient way to check the logging levels. Macro version have less functions calls during the whole process.
Log levels are following (from ndebug.h):
- log_always 1
- log_error 2
- log_warn 3
- log_info 4
- log_debug 5
EXAMPLE
Code logtest.c
#include <ndebug.h>
int main (int argc, char **argv)
{
tplog(5, "Hello from function logger");
TP_LOG(log_debug, "Hello from macro logger [logging level %d]", log_debug);
return 0;
}Sample run:
$ cc logtest.c -lnstd -lpthread -lrt -lm -I /include $ ./a.out t:USER:5:11064:000:20160928:100225252:/tplog.c:0412:Hello from function logger t:USER:5:11064:000:20160928:100225252:ogtest.c:0007:Hello from macro logger [logging level 5]
