intptr_t handle,
intptr_t config,
int attribute,
intptr_t attribute_value,
size_t attribute_size,
)[source]#

Gets an attribute of the Krylov configuration.

Parameters:

  • handle (intptr_t) – Library handle.

  • config (intptr_t) – Krylov configuration object.

  • attribute (TimePropagationApproachKrylovConfigAttribute) – Attribute to get.

  • attribute_value (intptr_t) – Pointer to store the attribute value.

  • attribute_size (size_t) – Size of the buffer in bytes.

Note

To compute the attribute size, use the itemsize of the corresponding data type, which can be queried using get_time_propagation_approach_krylov_config_attribute_dtype().
