Rb_io_getline question

Hi:

I am experimenting with some of the C io routines for the first
time and am getting a relocation error in rb_io_getline.

The C code is:

static VALUE
ff_cloop(self, infptr)
VALUE self, infptr;
{
VALUE str = Qnil;
VALUE rs = rb_str_new2("\n"); // Is this correct?
str = rb_io_getline(rs, infptr); // This line is causing the err
return Qnil;
}

The error I get is:
ld.so.1: /tools/apps/ruby/ruby-1.8.0/bin/ruby: fatal: relocation error:
file ./fastfile.so: symbol rb_io_getline: referenced symbol not found
Killed

And the ruby driver code is:

require 'fastfile’
file = ARGV.shift
ff = FastFile.new

File.open(file) { |f|
ff.cloop(f)
}

Can someone help me out here?
Thanks

      VALUE rs = rb_str_new2("\n"); // Is this correct?
      str = rb_io_getline(rs, infptr); // This line is causing the err

         str = rb_io_gets(infptr);

      return Qnil;
  }

The error I get is:
ld.so.1: /tools/apps/ruby/ruby-1.8.0/bin/ruby: fatal: relocation error:
file ./fastfile.so: symbol rb_io_getline: referenced symbol not found
Killed

rb_io_getline is a static function

Hmm, can you translate that? Does that mean it can’t be used or
that it needs to called differently (and if so, how)?

you can't use rb_io_getline() but rb_io_gets() do what you want if the
record separator is '\n'

It means that the function is “private” and only available to the file
in which it is defined. Whether there’s a way around this I’m not sure,
so I’ll let Guy pick it up from here. :slight_smile:

Thanks. Is it the same for rb_io_getline_fast?

Yes, rb_io_getline_fast is a static function

rb_io_gets(VALUE) is the same than rb_io_getline_fast(OpenFile *, '\n')
