Declared in <galanthus/c_api/gln_capi.h>.
GLN_API const gln_transaction_t* GLN_CALL gln_get_transaction_at(
const gln_transactions_t* in_transactions,

Parameters
| Name | Direction | Type | Nullability | Ownership |

in_transactions | input | const gln_transactions_t* | nullable | borrowed |
in_index | input | size_t | value | value |
Collection Semantics
Indexes are zero-based over the rows materialized in this gln_transactions_t view.
The returned row is borrowed from the typed transaction view. Row pointers and strings read from the row stay valid only while the owning backend result envelope is alive.
Notes
Passing NULL for in_transactions is allowed and returns NULL.
Indexes are zero-based. The accessor returns NULL when in_index >= gln_get_transactions_count(...).
The returned row is borrowed from the parent backend result envelope through the typed view and must not be released directly.
