hPutStrLn -package:ihaskell
The same as
hPutStr, but adds a newline character.
This operation may fail with the same errors, and has the same issues
with concurrency, as
hPutStr!
Write a ByteString to a handle, appending a newline byte.
Unlike
hPutStr, this is not atomic: other threads might write
to the handle between writing of the bytestring and the newline.
Write a ByteString to a handle, appending a newline byte.
The chunks will be written one at a time, followed by a newline. Other
threads might write to the
Handle in between, and hence
hPutStrLn alone is not suitable for concurrent writes.
Write a string to a handle, followed by a newline.
The same as
hPutStr, but adds a newline character.
Write data plus newline character.
Write a string like value
a to a supplied
Handle,
appending a newline character.
Write a string to a handle, followed by a newline
N.B.: implementations might not define this atomically. If the state
of being atomic is necessary, one possible solution is to convert a
string to an efficient type for which
hPutStrLn is atomic.
Given a list of strings, output a line containing each item, adding
newlines as appropriate. The list is not expected to have newlines
already.
