- What's this?
check_sizeof(type, headers = nil, opts = "", &b)
public
Returns the size of the given type. You may optionally specify additional headers to search in for the type.
If found, a macro is passed as a preprocessor constant to the compiler using the type name, in uppercase, prepended with ‘SIZEOF_’, followed by the type name, followed by ‘=X’ where ‘X’ is the actual size.
For example, if check_sizeof(‘mystruct’) returned 12, then the SIZEOF_MYSTRUCT=12 preprocessor macro would be passed to the compiler.
