menoh_model_get_variable_dims()

[enobufs]

In node-menoh, I wrote this helper function. It would be nice if there's a C-API function in menoh something similar (if possible) to the following:

int32_t size;
const int32_t *dims;
ec = menoh_model_get_variable_dims(model_handle, var_name, &size, &dims);

Where;

menoh_error_code  menoh_model_get_variable_dims(
    const menoh_model_handle model,
    const char* variable_name, 
    int32_t *size,
    const int32_t **dims);

It is sort of combining _get_variable_dims_size and _get_variable_dims_at all together without having to iterate over _dims_at function with its size...

Assumption: the dims values won't change unless the profile was altered by the app.

It's nice for efficiency to avoid repeated lookup with variable_name across multiple invocation of menoh_model_get_variable_dims_at (at least mentally).

I wonder how to manage the memory pointed by dims.

[msakai]

I assumed the memory is owned by the model.

[okdshin]

I see. I'll modify as that.

PR #41 is related as this PR change the type of dims.

[okdshin]

I've done.
