compile-foreign-type

Arguments: body &optional keys errorp

This function takes a foreign type specification (in the body argument) and converts it to an internal representation. It is not normally necessary to call this function since most foreign type functions pre-internalize the foreign type specifications which they accept. errorp defaults to t. If nil, nil is returned but no error is signaled if body specified an invalid type. keys is a list of attributes and defaults to nil. See def-foreign-type where acceptable attributes are listed.
