copyAddrToAddrNonOverlapping# :: Addr# -> Addr# -> Int# -> State# RealWorld -> State# RealWorld

copyAddrToAddrNonOverlapping# src dest len copies len bytes from src to dest. As the name suggests, these two memory ranges must not overlap, although this pre-condition is not checked.

Analogous to the standard C function memcpy, but with a different argument order.

Warning: this can fail with an unchecked exception.

Since: ghc-prim-0.11.0

setAddrRange# :: Addr# -> Int# -> Int# -> State# RealWorld -> State# RealWorld

setAddrRange# dest len c sets all of the bytes in [dest, dest+len) to the value c.

Analogous to the standard C function memset, but with a different argument order.

Warning: this can fail with an unchecked exception.

Since: ghc-prim-0.11.0
