* include/ruby/intern.h, thread_pthread.c (rb_reserved_fd_p,
RB_RESERVED_FD_P): added. This C API is to limit to access fds which are used by RubyVM internal. In this version of CRuby, return 1 if fd is communication pipe. If your application needs to close all file descriptors to preent resource leak, skip internal fds using this C API. We also define a macro RB_RESERVED_FD_P(fd). So you can write #ifndef RB_RESERVED_FD_P #define RB_RESERVED_FD_P(fd) 0 #endif for Ruby 1.9.2 or previous version to write compatible extensions. See [ruby-core:37727] * thread_win32.c (rb_reserved_fd_p): added (return 0 for any fds). * io.c (rb_io_initialize): raise ArgumentError if given fd is reserved by Ruby. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@32394 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
