Subject: [PATCH 1/2] make $fh->error report errors from both input and output
|
||
|
|

|
For character devices and sockets perl uses separate PerlIO objects
|
||
|
|
for input and output so they can be buffered separately.
|
||
|
|
|
||
|
|
The IO::Handle::error() method only checked the input stream, so
|
||
|
|
if a write error occurs error() would still returned false.
|
||
|
|
|
||
|
|
Change this so both the input and output streams are checked.
|
||
|
|
|
||
|
|
fixes #6799
