Build Warning: Non-Null Required

    ...: warning: null argument where non-null required

Many functions take pointers as arguments and require that the pointer never be NULL. To this end, you can declare function prototypes that instruct the compiler to do simple checks to make sure people do not incorrectly call the function with NULL values. This warning pops up when someone calls a function and they use NULL when they should not. Depending on the library, the function may actually crash (they told you not to use NULL after-all, so it's your fault :P).

You will need to read the code and fix it so that it does not incorrectly call the relevant functions with NULL values.
