linux - Why does strftime uppercase flag '^' not work? -

-

i have following command $(perl -e 'use posix;print strftime "%d-%^b-%y",localtime time-86400;') works on red hat linux box, not on sun solaris 9 box.

question 1: read here, '^' provided glibc... correct?

question 2: how find out why it's not working on solaris box? (and ultimately, how make work?)

solaris not linux, although it's unix :-), system calls behave differently on different system, that's why see lots of #ifdef in c programs. can compile this c example of time functions on redhat , solaris , see difference (convert %b %^b , see not print in uppercase). best solution use perl's uc function.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
