Don't you need to add NULL check on pool ptr since this function is exported?
What bearing does exporting a function have on whether it should check for NULL?
Given that this function returns size_t, it can't return an error number. So what value would it return if "pool" were NULL? It can only return a positive integer or zero.
Also, the argument should be const as the function doesn't modify the contents of "pool".
