Resolve issues while scanning for printer #22
Description
I scan with the following code example for printers. After about 40 rounds in the for loop the following error appears:
compat.c: write() failed: Bad file descriptor
ruby: compat.c:425: sdref_free: Assertion `__ret == 0' failed.
compat.c: write() failed: Broken pipe
compat.c: read() failed: EOF
Any ideas how to fix this? Looks like it is crashing in the avahi-lib in this line:
ASSERT_SUCCESS(write_command(sdref->main_fd, COMMAND_QUIT));
require 'dnssd'
service = '_http._tcp' #network printer
resolved = []
i = 1
while i <=100
DNSSD.browse service do |b|
DNSSD.resolve(b) do |r|
resolved << r
end
end
sleep 0.5
puts "***** Round #{i} *****"
resolved.each do |r|
puts r.fullname
end
i+=1
resolved = []
end
