- improved USB functions (linux)
- make use of fftw library when available
- improved memory handling in 64bit versions
- new parameter list types for CALL
......@@ -11,16 +11,28 @@ DESCRIPTION:
If you want to specify other types, please use prefixes:
D: -- double (8-Bytes)
F: -- float (4-Bytes)
L: -- long int, pointer (4-Bytes)
D: -- double (8 bytes)
F: -- float (4 bytes)
L: -- integer (4 bytes)
R: -- long integer (8 bytes)
W: -- short integer (2 bytes)
B: -- byte (1 byte)
P: -- pointer (4 bytes or 8 bytes, depending on the OS)
The Option P: behaves the same as L: on 32bit operating systems. But you
should use P: for pointers (VARPTR() etc...) into memory so that it can
be translated from X11-Basic internal 32bit representation to the 64bit
adresses on 64it operating systems.
The B: and W: options behave the same as the L: option.

CALL adr%,D:1.2,L:0,L:VARPTR(result(0))
