ANSI C : test return from calloc API

 

This question already has an answer here:

  • Why does malloc(0) return a non-null address in Windows? 5 answers

    • As the documentation from cppreference says:

    If size is zero, the behavior is implementation defined (null pointer may be returned, or some non-null pointer may be returned that may not be used to access storage)

    Just don't do that.
