Function clingo_sys::clingo_configuration_array_at

pub unsafe extern "C" fn clingo_configuration_array_at(
    configuration: *mut clingo_configuration_t, 
    key: clingo_id_t, 
    offset: usize, 
    subkey: *mut clingo_id_t
) -> bool

Get the subkey at the given offset of an array entry.

Note: Some array entries, like fore example the solver configuration, can be accessed past there actual size to add subentries. @pre The @link clingo_configuration_type() type@endlink of the entry must be @ref ::clingo_configuration_type_array.

Parameters:

• configuration the target configuration
• key the key
• offset the offset in the array
• subkey the resulting subkey

Returns whether the call was successful
