Declare second parameter as a string passed by reference. This'll pass pointer to the string into function. Anyway it's not a good idea to keep a pointer to VFP memory variable because VFP could change string location in memory when it's doing internal "garbage collection".

DECLARE RtlMoveMemory IN kernel32 As CopyMemory;    
    STRING  @ Destination,;    
    <b>String  @ Source, </b>;    
    INTEGER   nLength
lpBuffer = SPACE(100)
lcTemp = Getenv("temp")
= CopyMemory (@lpBuffer, @lcTemp, Len(lpBuffer))

Take a look at file#986and file#9557 for some related info.
