Subject: [ruby-core:51562] [ruby-trunk - Bug #7718] test_ioctl_linux fails on PPC and PPC64


Issue #7718 has been updated by vo.x (Vit Ondruch).


=begin
This is the output:
 # ./a.out 
 40045200

And here is my testing IRB session:

 # irb
 irb(main):001:0> File.open('/dev/urandom'){|f1|
 irb(main):002:1*         entropy_count = ""
 irb(main):003:1>         # get entropy count
 irb(main):004:1*         f1.ioctl(0x80045200, entropy_count)
 irb(main):005:1>       }
 Errno::EINVAL: Invalid argument - /dev/urandom
 	from (irb):4:in `ioctl'
 	from (irb):4:in `block in irb_binding'
 	from (irb):1:in `open'
 	from (irb):1
 	from /usr/bin/irb:12:in `<main>'
 irb(main):006:0> File.open('/dev/urandom'){|f1|
 irb(main):007:1*         entropy_count = ""
 irb(main):008:1>         f1.ioctl(0x40045200, entropy_count)
 irb(main):009:1> }
 => 0
 irb(main):010:0>
