unsafe
Overview
Package unsafe contains operations that step around the type safety of Go programs.
Packages that import unsafe may be non-portable and are not protected by the Go 1 compatibility guidelines.
Functions
Alignof
Alignof takes an expression x of any type and returns the required alignment of a hypothetical variable v as if v was declared via var v = x. It is the largest value m such that the address of v is always zero mod m. It is the same as the value returned by reflect.TypeOf(x).Align(). As a special case, if a variable s is of struct type and f is a field within that struct, then Alignof(s.f) will return the required alignment of a field of that type within a struct. This case is the same as the value returned by reflect.TypeOf(s.f).FieldAlign(). The return value of Alignof is a Go constant if the type of the argument does not have variable size. (See the description of Sizeof for a definition of variable sized types.)
