slot_type

Retrieve the field code of an object in a slot and, optionally, some other information

Behaviour

• Locate the object pointed to by the specified slot_no

• Determine its sf field code and return this, or some other information (see below) if flags are used

Definition

C

int64_t slot_type (
  	uint32_t slot_no,
  	uint32_t flags
);

Example

C

uint8_t txn_id[32];
int64_t bytes_written = 
    slot_id(txn_id, 32, 1); // assumes a txn is slotted into slot=1

Parameters

Name	Type	Description
slot_no	uint32_t	The slot number
flags	uin32_t	For normal operation this should be 0. To determine whether or not an STI_AMOUNT type contains a native (XRP) amount or a floating point (IOU) amount set to 1.

Return Code

Type	Description
int64_t	If flags is 0 then: The sf field code of the slotted object If flags is 1 then: 1 if and only if the slotted object is an STI_AMOUNT and the type of the amount is XRP. If negative, an error: DOESNT_EXIST - the specified slot_no does not contain an object. NOT_AN_AMOUNT - flags was set to 1 but the slotted object is not an STI_AMOUNT object
