mmap-go is a portable mmap package for the Go programming language.

This package is tested using GitHub Actions on Linux, macOS, and Windows. It should also work on other Unix-like platforms, but hasn't been tested with them. I'm interested to hear about the results.

I haven't been able to add more features without adding significant complexity, so mmap-go doesn't support mprotect, mincore, and maybe a few other things. If you're running on a Unix-like platform and need some of these features, I suggest Gustavo Niemeyer's gommap.

This package compiles on Plan 9, but its functions always return errors.
