/**
* Replace the previously stringshared pointer with another stringshared pointer.
*
* The string pointed by @a p_str must be previously stringshared or
* @c NULL and it will be eina_stringshare_del(). The new string must also
* be stringshared and will be passed to eina_stringshare_ref() and then assigned to @c *p_str.
* This function is identical to eina_stringshare_replace() except that it calls
* eina_stringshare_ref() instead of eina_stringshare_del()
*
* @param p_str pointer to the stringhare to be replaced. Must not be
* @c NULL, but @c *p_str may be @c NULL as it is a valid
* stringshare handle.
* @param news new string to replace with, may be @c NULL.
*
* @return #EINA_TRUE if the strings were different and thus replaced, #EINA_FALSE
* if the strings were the same after shared.
*
* @since 1.8
