v0.6.0

Added

• Support for linux/riscv64 added #15.

Changed

• Dependency github.com/ebitengine/purego updated (required for linux/riscv64).

v0.5.1

Fixed

• DefaultAbi had a wrong value on Windows ARM64.
• Missing extra field attached to Cif (Windows/macOS ARM64).
• Embedded libffi binaries have been updated to 3.5.1.

v0.5.0

Added

• The libffi shared libraries for Windows AMD64 and macOS AMD64/ARM64 are now embedded into this library (#12).
  The build tag ffi_no_embed or the environment variable FFI_NO_EMBED=1 can disable this feature.
• You can now retrieve the used libffi version (requires libffi 3.5.0 or newer):
  • func GetVersion() string
  • func GetVersionNumber() uint64
• Function func GetStructOffsets(abi Abi, structType *Type, offsets *uint64) Status implemented.

Changed

• Dependency github.com/ebitengine/purego updated.

v0.4.1

Fixed

• The dependency github.com/ebitengine/purego had to be upgraded to version 0.8.3 due to a bug in Go 1.23.9 and 1.24.3.

v0.4.0

Changed

• Fun.Call panics now, if the number of arguments doesn't match the prepared Cif.

v0.3.0

Added

• libffi's closure API has been implemented, which allows you to create C functions at runtime:
  • func ClosureAlloc(size uintptr, code *unsafe.Pointer) *Closure
  • func ClosureFree(writable *Closure)
  • func PrepClosureLoc(closure *Closure, cif *Cif, fun uintptr, userData, codeLoc unsafe.Pointer) Status
• The new types Fun and Lib can reduce boilerplate and eliminate platform-dependent code:
  • func (f Fun) Call(ret any, args ...any)
  • func Load(name string) (l Lib, err error)
  • func (l Lib) Close() error
  • func (l Lib) Get(name string) (addr uintptr, err error)
  • func (l Lib) Prep(name string, ret *Type, args ...*Type) (f Fun, err error)
  • func (l Lib) PrepVar(name string, nFixedArgs int, ret *Type, args ...*Type) (f Fun, err error)
• New method func (a Arg) Bool() bool added.
• Changelog file added.

Changed

• On Linux, libffi.so.7 was loaded when libffi.so.8 could not be found. This is no longer the case.
