-> (indirect Member Selector)
Go Up to Postfix Expression Operators Index
Syntax
postfix_expression->identifier
postfix_expression
must be of type pointer to structure or pointer to union.
identifier
must be the name of a member of that structure or union type.
The expression designates a member of a structure or union object. The value of the expression is the value of the selected member it will be an lvalue if and only if the postfix expression is an lvalue.
Remarks
You use the selection operator -> to access structure and union members.
Suppose that the object s
is of struct type S
and sptr
is a pointer to s
. Then, if m
is a member identifier of type M
declared in S
, this expression:
sptr->m
is of type M
, and represents the member object m
in s
.
The expression
s->sptr
is a convenient synonym for (*sptr).m
.
