# klogging

An easy-to-use C/C++ logging library

## Build and Install

```bash
make
sudo make install
sudo ldconfig
```

## Usage Example

--- *myprog.c* ---

```c
#include <klogging.h>

int main(int argc, char *argv[])
{
        KLOG_SET(argc, argv);

        KLOGA("I'm KLOGA");
        KLOGF("I'm KLOGF");
        KLOGE("I'm KLOGE");
        KLOGW("I'm KLOGW");
        KLOGI("I'm KLOGI");
        KLOGD("I'm KLOGD");
        KLOGV("I'm KLOGV");

        return 0;
}
```

Compile *myprog.c* with klogging library

```bash
gcc myprog.c -lklogging -o myprog
```

Run myprog

```
$ ./myprog
