| Summary | 0005154: #define Val_some |
| Description | OCaml C interface defines many macros to construct/access primitive ocaml values from C code. One thing that I often find missing and have to copy-paste myself in almost every binding is code to handle option type. |
| Additional Information | #define Val_none Val_int(0)
value Val_some(value v)
{
CAMLparam1(v);
CAMLlocal1(some);
some = caml_alloc_small(1, 0);
Field(some, 0) = v;
CAMLreturn(some);
}
#define Some_val(v) Field(v,0)
