Hi guys,
A little question about foreigners. I have this:
typedef struct JavaVMOption {
...
} JavaVMOption;
(define-foreign-record-type (jvm-option "JavaVMOption")
...)
typedef struct JavaVMInitArgs {
...
JavaVMOption *options;
} JavaVMInitArgs;
Then I need to define a binding to JavaVMInitArgs in which I need to
set more than one jvm-option in the options field.
- My fist attempt was:
(define-foreign-record-type (jvm-init-args "JavaVMInitArgs")
...
(jvm-option options jvm-init-args-options jvm-init-args-options-set!))
I can use jvm-init-args-options-set! to set one jvm-option, just using
(jvm-init-args-options-set! args option1). But I don't know how to set
a second one.
- Another alternative (doesn't work but I think could be theoretically
possible) is this:
(define-foreign-type struct-jvm-option "struct JavaVMOption") ; this
doesn't work (Error: illegal foreign argument type `JavaVMOption')
(define-foreign-record-type (jvm-init-args "JavaVMInitArgs")
...
(struct-jvm-option (options 2) jvm-init-args-options
jvm-init-args-options-set!))
and then use jvm-init-args-options-set! with an index.
Could you give me a hint?
Thanks!,
Regards,
Hugo
