Type Names
Type names are used in some declarators in the following ways:
In explicit conversions
As arguments to the sizeof operator
As arguments to the new operator
In function prototypes
In typedef statements
A type name consists of type specifiers such as int or the name of a class or struct, in combination with an abstract declarator, as described in Declarations and Abstract Declarators. The abstract declarator has the effect of modifying the base type to produce a pointer, reference or array type. It is not required if specifying a scalar type.
In the following example, the arguments to the strcpy_s function are supplied using their type names. In the case of the strSource argument, const char is the type specifier and * is the abstract declarator:
errno_t strcpy_s( char *strDestination, size_t numberOfElements, const char *strSource );
