Typedef declaration
Typedef declaration
The typedef declaration provides a way to declare an identifier as a type alias, to be used to replace a possibly complex type name.
The keyword typedef is used in a declaration, in the grammatical position of a storage-class specifier, except that it does not affect storage or linkage:
typedef int int_t; // declares int_t to be an alias for the type int
typedef char char_t, *char_p, (*fp)(void); // declares char_t to be an alias for char
// char_p to be an alias for char*
// fp to be an alias for char(*)(v
