 I'm trying to receive a simple
 structure from a shared library but
 get an Type Mismatch error saying...
 
   "wanted StructVersion, got Function instead in
 FMain:87"
 
 Before calling the extern function I declare the structure,
 variable
 and the library using...
 
   Public Struct StructVersion
       Major As Byte
       Minor As Byte
   End Struct
 
   Public Version As StructVersion
 
   Extern LIBVersion() As StructVersion In "libtest"
 
 But get the error when calling the function with...
 
   Version = LIBVersion
 
 I did find an older post made by Benoît and using the code
 given in that
 post results
 in the same error (i.e "wanted StructTm, got Function
 instead in FMain:107")
 
 --8<-----------------------------------------------------------------
 
 Public Struct StructTm
    tm_sec As Integer
    tm_min As Integer
    tm_hour As Integer
    tm_mday As Integer
    tm_mon As Integer
    tm_year As Integer
    tm_wday As Integer
    tm_yday As Integer
    tm_isdst As Integer
 End Struct
 
 Private Extern localtime(timep As Pointer) As StructTm In
 "libc:6"
