Porting for a pure C implementation

Hi @emilk ,

Thank you for this wonderful and super useful library.
I have a pure C application in which I would like to use this logging library. Do we have any C language port available for this library?

If not, please provide me some guidelines, I am interested to port this to pure C library.

No files, tests, or entry points are named. Start by reviewing the repository's existing C++ logging implementation and public API to determine the scope of a pure C port. Done would require either a clearly scoped C implementation or concrete porting guidelines, with the expected API and compatibility boundaries documented.
