О чём код?
// Package mmap provides memory mapped related utilities. package mmap import "os" // PageSize is the minimum allocation size. Allocations will use at // least this size and are likely to be multiplied up to a multiple of // this size. var PageSize = os.Getpagesize() // MustAlloc allocates size bytes and returns a slice containing them. If // the allocation fails it will panic. This is best used for // allocations which are a multiple of the PageSize. func MustAlloc(size int) []byte { mem, err := Alloc(size) if err != nil { panic(err) } return mem } // MustFree frees buffers allocated by Alloc. Note it should be passed // the same slice (not a derived slice) that Alloc returned. If the // free fails it will panic. func MustFree(mem []byte) { err := Free(mem) if err != nil { panic(err) } }
