Once again I���m struggling with NativeBoost. I���m trying to use optCoerceNilToNull with this function:

^self call: #(LGitReturnCodeEnum git_commit_create(

LGitId * theCommitId,��

LGitRepository repo,

String update_ref,��

LGitSignature * theAuthor,

LGitSignature * theCommitter,

String message_encoding,

String theMessage,

LGitTree theTree,

int parent_count,��

LGitCommit * parentsPointer)) options: #( optCoerceNilToNull )

The last argument can be NULL, per documentation, (no parents).

LGitCommit is a subclass of NBExternalObject and apparently NBExternalObjctType>>pushAsPointer: does *not* use the optCoerceNilToNull option (the super implementation in NBExternalType>>pushAsPointer: however does). The upshot of course is that the call fails with ���an instance of LGitCommit expected���.

My questions:

- The documentation says:

"#optCoerceNilToNull"

"passing nil as a pointer-type argument, converts it to C NULL ���

but apparently this doesn���t apply to every pointer type. Should the documentation be updated?

- Why does NBExternlObjectType not use optCoerceNilToNull? I don���t want to use tricks to pass null if I don���t have to.

- Related: there are instances where even non-pointer arguments are allowed to be NULL. Why does optCoerceNilToNull only work for pointer types?

Igor! Help! :)

Cheers,

Max
