in mac program, want copy file located in /private/var/db/dslocal/nodes/default/users/xx.plist to disc.

presumably failed, , is. use api of copyitematpath:topath:error: this, , nslog out error infomation: says /private/var/db/dslocal/nodes/default/users/xx.plist this file couldn't opened because don't have permission view it. operation couldn't completed, permission denied.

and can introduce me documentations or sample codes should read solve problem? please!

you're trying requires user administrator (or root), requires elevated access. way go in osx factor out privileged code separate executable run elevated permissions, after having prompted user administrator's credentials.

take @ osx authorization services prompting user: https://developer.apple.com/library/mac/#documentation/security/reference/authorization_ref/reference/reference.html

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).
