| The kind of the call. | |
| uint32_t | flags |
| Additional flags modifying the call execution behavior. | |

| The present depth of the message call stack. | |
| int64_t | gas |
| The amount of gas available to the message execution. | |
| evmc_address | recipient |
| The recipient of the message. | |
| evmc_address | sender |
| The sender of the message. | |
| const uint8_t * | input_data |
| The message input data. | |
| size_t | input_size |
| The size of the message input data. | |

| The amount of Ether transferred with the message. | |
| evmc_bytes32 | create2_salt |

The message describing an EVM call, including a zero-depth calls from a transaction origin.
Most of the fields are modelled by the section 8. Message Call of the Ethereum Yellow Paper.
| evmc_address evmc_message::code_address |
The address of the code to be executed.
For EVMC_CALLCODE or EVMC_DELEGATECALL this may be different from the evmc_message::recipient. Not required when invoking evmc_execute_fn(), only when invoking evmc_call_fn(). Ignored if kind is EVMC_CREATE, EVMC_CREATE2 or EVMC_EOFCREATE.
In case of EVMC_CAPABILITY_PRECOMPILES implementation, this fields should be inspected to identify the requested precompile.
Defined as c in the Yellow Paper.
| size_t evmc_message::code_size |
| evmc_bytes32 evmc_message::create2_salt |
The optional value used in new contract address construction.
Needed only for a Host to calculate created address when kind is EVMC_CREATE2 or EVMC_EOFCREATE. Ignored in evmc_execute_fn().
| int32_t evmc_message::depth |
| uint32_t evmc_message::flags |
| int64_t evmc_message::gas |
| const uint8_t* evmc_message::input_data |
| size_t evmc_message::input_size |
| enum evmc_call_kind evmc_message::kind |
| evmc_address evmc_message::recipient |
The recipient of the message.
This is the address of the account which storage/balance/nonce is going to be modified by the message execution. In case of EVMC_CALL, this is also the account where the message value evmc_message::value is going to be transferred. For EVMC_CALLCODE or EVMC_DELEGATECALL, this may be different from the evmc_message::code_address.
Defined as r in the Yellow Paper.
| evmc_address evmc_message::sender |
The sender of the message.
The address of the sender of a message call defined as s in the Yellow Paper. This must be the message recipient of the message at the previous (lower) depth, except for the EVMC_DELEGATECALL where recipient is the 2 levels above the present depth. At the depth 0 this must be the transaction origin.
| evmc_uint256be evmc_message::value |
The amount of Ether transferred with the message.
This is transferred value for EVMC_CALL or apparent value for EVMC_DELEGATECALL. Defined as v or v~ in the Yellow Paper.
