btck_script_pubkey

Verify if the input at input_index of tx_to spends the script pubkey under the constraints specified by flags. If the btck_ScriptVerificationFlags_WITNESS flag is set in the flags bitfield, the amount parameter is used. If the taproot flag is set, the precomputed data must contain the spent outputs.

Parameters

Nullable if the taproot flag is not set. Otherwise, precomputed data for tx_to with the spent outputs must be provided.

input_index [in]
