Detailed Description

Thread safe printing API.

Provides replacements for printf and fprintf with the two functions prints and fprints, standing for "print safe".

Both functions are variadic and wrap the standard print functions, meaning their use is identical and as such the documentations for printf and fprintf can be used as reference.

The functions also allow writing to any IO stream, prints is simply a call to fprints where the IO stream is fixed to stdout,
