windows - When does System.getProperty("java.io.tmpdir") return "c:\temp" -


just curious when system.getproperty("java.io.tmpdir") returns "c:\temp". according java.io.file java docs-

the default temporary-file directory specified system property java.io.tmpdir. on unix systems default value of property typically "/tmp" or "/var/tmp"; on microsoft windows systems typically "c:\temp". different value may given system property when java virtual machine invoked, programmatic changes property not guaranteed have effect upon the temporary directory used method.

but in case- 

system.out.println(system.getproperty("java.io.tmpdir"));

always returns-

c:\users\admin\appdata\local\temp\ i.e. %temp%

in conditions return "c:\temp"?

edited: if change %temp% c:\temp c:\temp, right? documentation shows c:\temp instead of c:\temp.

in ms windows temporary directory set environment variable temp. in xp, temporary directory set per-user local settings\temp.

if change temp environment variable c:\temp, same when run :

system.out.println(system.getproperty("java.io.tmpdir"));

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
