c++ - copyfile function on Mac OS X -


i working on program copies files , folders point point b, it's pretty simple part. decided use copyfile function actual copying because handles of metadata. whatever reason there many files can't copy, if i'm running root. example file can't copied /usr/share/emacs/22.1/etc/babyl

i don't know why this. file good, can go in finder , copy , paste other ordinary file. there permission issue missing? seems system files, not of them. consistent in , not copy.

the actual function call looks copyfile(filepath, destpath, gstate, copyfile_data | copyfile_acl | copyfile_stat | copyfile_xattr); error i'm getting not useful, io error 5.

is there missing causes not work files? or copyfile not certian things? there better ways copyfile copy files , of attributes/metadata?

please don't suggest other programs copy files, that's not i'm here for. thanks!

you going have dig deeper find problem, fortunately can dig inside copyfile() itself. apple provides full source can link code , trace through find problem.

note: may have tweak source little compile, straightforward enough so. if try , stuck ask question details of you've tried , what's gone wrong, you.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
