Another (IMHO more elegant) solution would be a union, where you lay your char array over your struct. Up0TrueDown Radoslav Marinov10 年多前in reply toChester Gillon Intellectual1000points Since the pointers are ...

struct student{ char name[50]; int age; int rollno; }; Here, structis the keyword to define a structure. studentis the name of the structure. nameis the first structure member to store age with maximum of 50 characters,ageis second structure member to store age of the student, androll...
Thenewkeyword takes a type as an argument, allocates enough memory to fit a value of that type and returns a pointer to it. newkey.go package main import ( "fmt" "reflect" ) type User struct { name string occupation string }

Since this is used in very minimal number of cases I propose that we document that conversion from unsafe.Pointer to *struct{} and backwards is always valid. That is way we can always get a type which satisfies *T contract and is safe to use, because dereferencing *struct{} gives you ...
