maxsize

uint32_t spa_data::maxsize

max size of data

type

uint32_t spa_data::type

memory type, one of enum spa_data_type, when allocating memory, the type contains a bitmask of allowed types.

SPA_ID_INVALID is a special value for the allocator to indicate that the other side did not explicitly specify any supported data types. It should probably use a memory type that does not require special handling in addition to simple mmap/munmap.
