To compile

1. clone this repository using git.
2. build using cmake
   1. cd to source directory
   2. mkdir Release
   3. cd Release
   4. cmake -DCMAKE_BUILD_TYPE=Release ..
   5. make

Can also change Release for Debug

Guidelines

To implement a new public interface:

1. add the function declaration in respective .h file
2. implementation writen in src/ folder and quote the .h file using #include"../XXXX.h"

To write a new test:

1. write the test function in testcases.c as a void func(void)
2. add the test description to tNames and the function to tFuncs

To use debug print:

• DEBUG_PRINT(...) works the same way as fprintf(stderr,...)
  • will be disabled #ifndef DEBUG
  • will be disabled when building as Release
