Typedefs

typedef-definition:
typedef type-specifier declarator-list ;

You can use typedefs to provide convenient names for complicated types. Once you define it, use a typedef as a type specifier (like int) in any declaration. A typedef definition looks just like a variable definition, except that the keyword typedef appears before the type specifier. The name of the typedef being defined appears instead of the variable name, and the typedef has the same type the variable would have had.

Typedefs only serve as abbreviations. They always create types that could be made in some other way. A variable declared using a typedef is just the same as a variable declared using the full specification. For example:

typedef short *NAME_LIST; NAME_LIST nl, narray[20];
is equivalent to

short *nl, *narray[20];
