- (bind-opaque-type TYPENAME SCHEMETYPE)syntax
Similar to bind-type, but provides automatic argument- and result conversions to wrap a value into a structure:
(bind-opaque-type myfile (pointer "FILE"))
(bind "myfile fopen(char *, char *);")
(fopen "somefile" "r") ==> <myfile>
(bind-opaque-type TYPENAME TYPE) is basically equivalent to (bind-type TYPENAME TYPE TYPE->RECORD RECORD->TYPE) where TYPE->RECORD and RECORD->TYPE are compiler-generated conversion functions that wrap objects of type TYPE into a record and back.
