Description

GHC C strings definitions (previously in GHC.Base). Use GHC.Exts from the base package instead of importing this module directly.

Synopsis

unpackCString# :: Addr# -> [Char]
unpackAppendCString# :: Addr# -> [Char] -> [Char]
unpackFoldrCString# :: Addr# -> (Char -> a -> a) -> a -> a
cstringLength# :: Addr# -> Int#
unpackCStringUtf8# :: Addr# -> [Char]
unpackAppendCStringUtf8# :: Addr# -> [Char] -> [Char]
unpackFoldrCStringUtf8# :: Addr# -> (Char -> a -> a) -> a -> a
unpackNBytes# :: Addr# -> Int# -> [Char]

Ascii variants

unpackCString# :: Addr# -> [Char] Source #

unpackAppendCString# :: Addr# -> [Char] -> [Char] Source #

unpackFoldrCString# :: Addr# -> (Char -> a -> a) -> a -> a Source #

cstringLength# :: Addr# -> Int# Source #

Compute the length of a NUL-terminated string. This address must refer to immutable memory. GHC includes a built-in rule for constant folding when the argument is a statically-known literal. That is, a core-to-core pass reduces the expression cstringLength to the constant 5#.
