module CIO

For documentation - C library that stands either for C Input/Output or Cooplib Input/Output. Contains functions for IO that are much faster than the ruby standard functions

Public Instance Methods

Exposes the #list_dirs method to ruby

VALUE rb_list_dirs(VALUE self, VALUE directory, VALUE level)
{
    VALUE r_string_directory = StringValue(directory);

    char *dir = RSTRING_PTR(r_string_directory);
    int lev = FIX2INT(level);

}

read_file(*args) click to toggle source

Exposes read_file_base to ruby

VALUE rb_read_file_base(int argc, VALUE *argv, VALUE self)

        VALUE r_string = rb_str_new2(buffer);
        free((void *)buffer);
        return r_string;
}

write_new_file(p1, p2) click to toggle source

Exposes the #write_new_file function to ruby
