index of the nth instance of test in src.を integer で返します。

• list	src	–	what to search in (haystack)
• list	test	–	what to search for (needles)
• list	instance	–	which instance (needle) to return

If test is not found in src, -1 is returned.
The index of the first entry in the list is 0
An expansion of llListFindList which adds an instance parameter to select the nth match to test parameter.
llListFindListNext(src, test, 0); is functionally equivalent to llListFindList(src, test);
Given a list like [ 'Resident', 'Alexia', 'Resident', 'Bob', 'Resident', 'Steve', 'Resident', 'Evil' ] using a test of [ 'Resident' ] and an instance of 0, 1, 2, 3 would return indices of 0, 2, 4, and 6 respectively. Selecting the 4th or greater instance will not be found and will return -1.
Reverse indexing is also supported. Using an instance of -1, -2, -3, -4 would respectively return 6, 4, 2, 0 And -5 and lower would again return -1
If test is found at the last index in src the positive index is returned (5th entry of 5 returns 4).

警告

• Strict type matching and case sensitivity is enforced.
  • "1" != 1
  • "1.0" != 1.0
  • 1 != 1.0
  • "a822ff2b-ff02-461d-b45d-dcd10a2de0c2" != (key)"a822ff2b-ff02-461d-b45d-dcd10a2de0c2"
  • "Justice" != "justice"
• If test is an empty list the value returned is 0 rather than -1.
