reproc
A cross-platform (C99/C++11) process library
...The main use case is executing command line applications directly from C or C++ code and retrieving their output. reproc consists out of two libraries: reproc and reproc++. reproc is a C99 library that contains the actual code for working with external programs. reproc++ depends on reproc and adapts its API to an idiomatic C++11 API. It also adds a few extras that simplify working with external programs from C++. -

Expat
Fast streaming XML parser written in C99 with >90% test coverage
...Expat excels with files too large to fit RAM, and where performance and flexibility are crucial. There are a number of applications, libraries, and hardware using Expat, as well as bindings and 3rd-party wrappers. Expat is packaged everywhere. This is Expat, a C99 library for parsing XML 1.0 Fourth Edition, started by James Clark in 1997. Expat is a stream-oriented XML parser. This means that you register handlers with the parser before starting the parse. These handlers are called when the parser discovers the associated structures in the document being parsed. A start tag is an example of the kind of structure for which you may register handlers. -

sj.h
A tiny little JSON parsing library
sj.h is a tiny JSON parsing library written in C99 for developers who want a minimal, allocation-free way to walk through JSON data. It is intentionally small, around a few hundred lines or less depending on how it is counted, and keeps state minimal so it can fit into constrained environments. The library does not try to own every part of JSON handling; instead, it leaves number conversion and string interpretation to the user. -

libCEED
CEED Library: Code for Efficient Extensible Discretizations
libCEED provides fast algebra for element-based discretizations, designed for performance portability, run-time flexibility, and clean embedding in higher-level libraries and applications. It offers a C99 interface as well as bindings for Fortran, Python, Julia, and Rust. While our focus is on high-order finite elements, the approach is mostly algebraic and thus applicable to other discretizations in factored form, as explained in the user manual and API implementation portion of the documentation. One of the challenges with high-order methods is that a global sparse matrix is no longer a good representation of a high-order linear operator, both with respect to the FLOPs needed for its evaluation, as well as the memory transfer needed for a matvec. ... -

Criterion
A cross-platform C and C++ unit testing framework for the 21st century
Most test frameworks for C require a lot of boilerplate code to set up tests and test suites -- you need to create a main, then register new test suites, then register the tests within these suites, and finally call the right functions. This gives the user great control, at the unfortunate cost of simplicity. Criterion follows the KISS principle, while keeping the control the user would have with other frameworks. Supports parameterized tests and theories. Progress and statistics can be... -
