A secure C string library that's designed for embedded development in mind.
This is yet another implementation of the classic {length, char pointer} structure which provides much better security than char* as it prevents buffer overflows by automating changes in string length. The programmer no longer needs to worry about this. This particular implementation was designed so it can be used either with stack based preallocated buffers or dynamically allocated and resizable buffers, depending on the hardware requirements.
It's quite simple and does nothing really fancy so you can easily understand what it does, but when I wrote it in 2009, it was fully tested for embedded hardware with small memory requirements. It passes Valgrind and has been successfully used in production. Unfortunaly I no longer have the tests suite so you'll have to write your own before using this library.
Enjoy !
