ptype

ptype
ptype expression
ptype type-name

Print the full definition of a type. This differs from whatis, in that whatis prints only type names, while ptype gives a full description. With no argument (the first syntax), print the type of the last value in the value history. This is equivalent to ptype $. With expression (the second syntax), print the type of expression. Note that the expression is not evaluated. No operators with side effects (such as ++, or a function call) execute. The third syntax prints the type of type-name, which is either the name of a type or one of the keywords class, enum, struct, or union, followed by a tag. See also whatis.
