Simple example:
#include <stdio.h>
#include <strings.h>
#include <errno.h>
#include "libinjection.h"
#include "libinjection_sqli.h"
int main(int argc, const char* argv[])
{

const char* input = argv[1];
size_t slen = strlen(input);
/* in real-world, you would url-decode the input, etc */

issqli = libinjection_is_sqli(&state);

}
return issqli;

Versions are listed as "major.minor.point"
Major are significant changes to the API and/or fingerprint format. Applications will need recompiling and/or refactoring.
Minor are C code changes. These may include
- logical change to detect or suppress
- optimization changes
- code refactoring
Point releases are purely data changes. These may be safely applied.
The continuous integration results at https://travis-ci.org/client9/libinjection tests the following:
- build and unit-tests under GCC
- build and unit-tests under Clang
- static analysis using clang static analyzer
- static analysis using cppcheck
- checks for memory errors using valgrind
- code coverage online using coveralls.io
