Expand description

munmap(ptr, len)—Remove a memory mapping.

§Safety

ptr must be aligned to the applicable page size, and the range of memory starting at ptr and extending for len bytes, rounded up to the applicable page size, must be valid to mutate with ptr’s provenance. And there must be no Rust references referring to that memory.
