### Overview

Stand-alone, portable C libraries. 

Each folder is independent and contains a header and a source file.  
There is no build, just copy paste *.h *.c files into your project.

### Test

Although I use on Linux mostly, CI runs with some combination of 

<pre>
OS         : Linux, MacOS, FreeBSD and Windows  
Compilers  : GCC, Clang, MSVC  
Arch       : x64, aarch64, armv6, armv7, ppc64le, s390x  
Sanitizers : valgrind and clang/gcc sanitizers(address, undefined, thread)
</pre>

To run all tests :
<pre>
#with valgrind
mkdir build; cd build;
cmake .. && make && make check

#with address sanitizer
mkdir build; cd build;
cmake .. -DSANITIZER=address && make && make check

#with undefined sanitizer
mkdir build; cd build;
cmake .. -DSANITIZER=undefined && make && make check
</pre>
