When it rains, it pours i/o all over Erlang

klacke adds to the erlang i/o discussion as he did with the regexp discussion, with a faster library...

Originally at Bluetail, we had some serious problems with high performance file I/O, especially line oriented such.

I then wrote a portable (yes win32 too) linked in driver for fast FILE I/O. It's based on an old and hacked version of the BSD FILE* interface. It's called bfile and we've been using it in pretty much all projects during the past 8 years. I've prepared a tarball of it at

2> bfile:load_driver().
ok
4> {ok, Fd} = bfile:fopen("Makefile", "r").
{ok,{bfile,#Port<0.98>}}
5> bfile:fgets(Fd).
{line,<<10>>}
6> bfile:fgets(Fd).
{line,<<10>>}
7> bfile:fgets(Fd).
{line,<<97,108,108,58,32,10>>}
14> bfile:fread(Fd, 10000).
