Amount Semantics
Returns the provider's credit-line amount text when supplied. Read it with gln_get_balance_currency unless the provider string itself carries currency details.
NULL means the materialized balance row has no credit-line field.
Notes
Passing NULL for in_balance is allowed and returns NULL.
NULL means the provider did not supply this optional field for the row.
The returned pointer is borrowed from the owning backend result envelope and becomes invalid when that envelope is destroyed.
