Windows byte typedef

To reuse the FlagType name for an identifier, a structure member, or a union member, the type must be provided:. This declaration is taken to be an illegal declaration like. You can declare any type with typedef, including pointer, function, and array types.

You can declare a typedef name for a pointer to a structure or union type before you define the structure or union type, as long as the definition has the same visibility as the declaration. One use of typedef declarations is to make declarations more uniform and compact. To use typedef to specify fundamental and derived types in the same declaration, you can separate declarators with commas. The following example provides the type DRAWF for a function returning no value and taking two int arguments:.

The typedef declaration can be used to redeclare the same name to refer to the same type. The program PROG. As long as both declarations refer to the same type, such redeclaration is acceptable.

A typedef cannot redefine a name that was previously declared as a different type. Therefore, if FILE2. H contains. Ask Question. Asked 6 years, 11 months ago. Active 6 years, 11 months ago.
