Declared in <galanthus/c_api/gln_capi.h>.
GLN_API const gln_balance_t* GLN_CALL gln_get_balance_at(
const gln_balances_t* in_balances,

Returns the balance row at in_index from a typed gln_balances_t view.
Return
Returns the borrowed row or entry at in_index, or NULL when the handle is NULL or the index is out of range.

Parameters
| Name | Direction | Type | Nullability | Ownership |
|---|---|---|---|---|
in_balances | input | const gln_balances_t* | nullable | borrowed |
in_index | input | size_t | value | value |
Collection Semantics
Indexes are zero-based over the rows materialized in this gln_balances_t view.
The returned row is borrowed from the typed balance 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_balances is allowed and returns NULL.
Indexes are zero-based. The accessor returns NULL when in_index >= gln_get_balances_count(...).
The returned row is borrowed from the parent backend result envelope through the typed view and must not be released directly.
