Enumeration Values

MmapEnabled = 0

Use memory mapping to read the content of the file.

The destination buffer TBLArray<> would be configured to use the memory mapped buffer instead of allocating its own.

---

MmapAvoidSmall = 1

Avoid memory mapping of small files.

The size of small file is determined by Blend2D, however, you should expect it to be 16kB or 64kB depending on host operating system.

---

MmapNoFallback = 3

Do not fallback to regular read if memory mapping fails. It's worth noting that memory mapping would fail for files stored on filesystem that is not local (like a mounted network filesystem, etc...).
