CValueSet:GetKeyAt

The GetKeyAt method returns the string key at a specified index in the CValueSet.

strKey = CValueSet:GetKeyAt( nIndex )

Where nIndex is an integer in the CValueSet, ranging from 1 to CValueSet:Count. If the index is invalid, nil is returned.

Returns the strKey string key at the specified index.

On failure, nil is returned.

The following example creates a CValueSet S and adds members to it, then returns the value at the specified index:

S = new_valueset("integer")	-- constructor for a set of type "integer"
S:Add( "key 1", 15 )	-- add a key and value
S:Add( "key 2", -7125 )	-- add a key and value
S:Add( "key 3", 9 )	-- add a key and value
n = 3	-- fetch the data at index 3
Printf("Key[%d]= %s",n, S:GetKeyAt(n))	-- result: Key[3]= key_3
