Behaviour

  • Write the 20 byte Account ID to the write_ptr

Definition

int64_t hook_account (
    uint32_t write_ptr,
    uint32_t write_len
);

Example

uint8_t hook_acc_id[20];
int64_t bytes_written = 
    hook_account(hook_acc_id, 20);

Parameters

NameTypeDescription
write_ptruint32_tPointer to a buffer of a suitable size to store the output. Should be at least 20 bytes.
write_lenuint32_tLength of the output buffer.

Return Code

TypeDescription
