Language.C.Inline.Unsafe
Description
unsafe variants of the Language.C.Inline quasi-quoters, to call the C code
unsafely in the sense of
https://www.haskell.org/onlinereport/haskell2010/haskellch8.html#x15-1590008.4.3.
In GHC, unsafe foreign calls are faster than safe foreign calls, but the user
must guarantee the control flow will never enter Haskell code (via a callback
or otherwise) before the call is done.
This module is intended to be imported qualified:
import qualified Language.C.Inline.Unsafe as CU
Synopsis
- exp :: QuasiQuoter
- pure :: QuasiQuoter
- block :: QuasiQuoter
Documentation
exp :: QuasiQuoter Source #
C expressions.
pure :: QuasiQuoter Source #
Variant of exp, for use with expressions known to have no side effects.
BEWARE: use this function with caution, only when you know what you are
doing. If an expression does in fact have side-effects, then indiscriminate
use of pure may endanger referential transparency, and in principle even
type safety.
block :: QuasiQuoter Source #
C code blocks (i.e. statements).
