accept

Accept the originating transaction and commit any changes the hook made.

Last updated 2 months ago

Concepts

  • Execution Order

Behaviour

End the execution of the hook with status: success.

  • Record a return string and return code in transaction metadata.

  • Commit all state changes.

  • Submit all emit() transactions.

  • Allow originating transaction to continue.

🚧Caution

If the originating transaction is stopped for some other reason then this accept becomes a rollback. See: Execution Order.

Definition

int64_t accept (
    uint32_t read_ptr,
    uint32_t read_len,
    uint64_t error_code
);
function accept(msg: string, code: number): number

Example

accept("Success", 7, 100);
accept('Success', 100)

Parameters

Name
Type
Description

read_ptr

uint32_t

Pointer to a return string to be stored in execution metadata. This is any string the hook-developer wishes to return with the acceptance. May be null.

read_len

uint32_t

The length of the return string. At most 32. May be null.

error_code

uint64_t

A return code specific to this hook to be stored in execution metadata. Similar to the return code of an application on a *nix system. By convention success is zero.

Name
Type
Description

msg

string

String to be stored in execution metadata. This is any string the hook-developer wishes to return with the acceptance. May be null.

code

number

A return code specific to this hook to be stored in execution metadata. Similar to the return code of an application on a *nix system. By convention success is zero.

Return Code

Type
Description

int64_t

Accept ends the hook, therefore no value is returned to the caller. By convention all Hook APIs return int64_t, but in this case nothing is returned.

Type
Description

number

Accept ends the hook, therefore no value is returned to the caller. By convention all Hook APIs return a number, but in this case nothing is returned.
