Issue #3752 has been updated by Aaron Patterson.
Status changed from Assigned to Rejected
If you pass a wrong pointer to a function, it will segv just like the C code would segv. DL is not meant to protect you from errors you could also make in C.
Here is an example of doing a null check, but with a crash. Provide a good file to taglib, and it won't crash.
require 'dl'
require 'dl/import'
module Foo
extend DL::Importer
dlload '/opt/local/lib/libtag_c.dylib'
extern 'void* taglib_file_tag(void*)'
extern 'void* taglib_file_new(char*)'
end
taglib_file = Foo.taglib_file_new(ARGV[0] || 'foo')
if taglib_file.null?
puts "bad file"
Foo.taglib_file_tag(taglib_file) # This will SEGV because it's a NULL pointer
else
file_tag = Foo.taglib_file_tag(taglib_file)
end
