Hi people.
I needed a function to split a string into a list. My first func used
Ecore_List * as return value, and dourse said me that's not really good.
He said me to return a char ** so i did it. And i put it under ecore_str.
The patch have two functions. The one to allocate the array of ptr. And
the second to free it.
Their's work as the glib's funcs ones.
I hope you will like it.
