\section thread_safety Thread safety
|
||||
|
||||
All calls to functions that take VmaAllocator as first parameter are safe to
|
||||
call from multiple threads simultaneously, synchronized internally when needed.
|
||||
- The library has no global state, so separate VmaAllocator objects can be used
|
||||
independently.
|
||||
- By default, all calls to functions that take VmaAllocator as first parameter
|
||||
are safe to call from multiple threads simultaneously because they are
|
||||
synchronized internally when needed.
|
||||
- When the allocator is created with VMA_ALLOCATOR_EXTERNALLY_SYNCHRONIZED_BIT
|
||||
flag, calls to functions that take such VmaAllocator object must be
|
||||
synchronized externally.
|
||||
- Access to a VmaAllocation object must be externally synchronized. For example,
|
||||
you must not call vmaGetAllocationInfo() and vmaDefragment() from different
|
||||
threads at the same time if you pass the same VmaAllocation object to these
|
||||
functions.
