parameters
il:object item list
item:int item to add
item_value:str value to add
item_length:int length of the buffer (the resulting string length is one byte less)
returns
None

addstrn(il:object, item:int, item_value:str, item_length:int)->None

Adds the specified space-expanded string to the item list. If the item_value is longer than the item_length, it will be truncated.

parameters
il:object item list
item:int item to add
item_value:str value to add
item_length:int length of the buffer
returns
None

getstr(il:object, index:int, flag:int)->str

Gets the string at the specified index in the item list.

parameters
il:object item list
index:int index of the item to get
flag:int if set to 1, the first byte of the resulting string is the length of the string
returns
String

addbin(il:object, item:int, item_value:int, item_offset:int, item_len:int)->None

Adds a new binary item to the list. It will be interpreted as a string.

parameters

item:int item to add
item_value:int value to store
item_offset:int starting byte
item_len:int amount of bytes
returns
None

getbyte(il:object, index:int, item_offset:int)->int
