If I run this code, when it invocates GetFullPathName that produces an error "Too many arguments" and I don't know why

DECLARE INTEGER GetFullPathName IN WIN32API kernel32;
    STRING    lpFileName,;
    INTEGER   nBufferLength,;
    STRING  @ lpBuffer,;
    INTEGER @ lpFilePart

lpFileName = "foxuser.dbf"
nBufferLength = 250
lpBuffer = SPACE(nBufferLength)
lpFilePart = 0
    
lnResult = GetFullPathName (lpFileName, nBufferLength, @lpBuffer, @lpFilePart)
IF lnResult > 0 And lnResult <= nBufferLength
    lpBuffer = Left(lpBuffer, lnResult-1)
    ? lpBuffer
ENDIF
