Description

Registers the callback function with msPTI to allocate the storage space of the activity buffer. When using the Activity API, a user (subscriber) needs to customize this function and register it with msPTI. When the storage space of the activity buffer is insufficient, msPTI calls this function to allocate new storage space.
