i'm trying convert program in c java. don't know c programming, i'd understand bit btw. well i've got functions in c: static int memcmp( byte *a, byte *b, int len) { int i; (i = 0; < len; i++) if (a[i] != b[i]) return 0; return 1; } static int rfind(byte *data, int pos, int leng) { int i; (i = pos - leng; > -1; i--) if (memcmp(data+i, data+pos, leng)) return i; return pos; } that can't workout. seems function memcmp compare 2 blocks of memory. when size of data: printf("size %d \n", sizeof(data)); i got 8 result while orignal size can 32 or 40 (any documentation pointers welcome). anyone me translate bit java have gratitude (and more). thanks java doesn't have pointers, can't translate code directly. in c, can treat pointers arrays, whereas in java need use indexes same array. more or less direct translation can come with: public int rfind(byte[]...

this problem, have main view shows 1 button, pressing button view shown. view has button, when button push current view finishs , control backs previous view. to show second view use startactivityforresult, put code here. private void startnewview() { intent = new intent(getapplicationcontext(), newview.class); startactivityforresult(it,view_id); } the view called has button event, here code button b = (button) findviewbyid(r.id.close); b.setonclicklistener(new view.onclicklistener() { public void onclick(view v) { setresult(result_ok); finish(); } }); and finally, method onactivityresult in main view, here code protected void onactivityresult(int requestcode, int resultcode, intent data) { super.onactivityresult(requestcode, resultcode, data); if(requestcode == view_id && resultcode == result_ok) { tv = (textview) findviewbyid(r.id.tv); tv.settext("the...

let's want make simple project tracking system. manager can create project. can create tasks project. team members can record hours work each task or project whole. is following design t_timesheet table idea? timesheet_id - primary key, autoincrement project_id - not null, foreign key constraint t_project task_id - nullable, foreign key constraint t_task user_id - not null, foreign key constraint t_user hours - decimal or should this: timesheet_id - primary key, autoincrement task_id - not null, foreign key constraint t_task user_id - not null, foreign key constraint t_user hours - decimal in second option, intend have record in t_task labelled "miscellaneous items" foreign key relevant t_project record. i'll able track hours project aren't particular task. are of ideas above good? better? while believe nullable foreign keys have place in relational databases, in case tend towards second option. forces project manager explicitly ...

(even if there isnt error). how can solve this? option create global var , mark when leave string state , hack yy_user fix itself? kind of want avoid that. cleaner @ next letter or token, possible? in flex, can "peek ahead" @ future tokens using / lookahead operator. rule like ab/cd will match 'ab' input if , if followed 'cd'. means flex matches 'cd' rule, pushes input buffer before calling action rule, yytext contains 'ab' when see it, , 'cd' read again ...

let's have model, example user, , want merge 2 instances of model, merge user2 user1. explicitly mean: if field filled in user1, should remain same if field missing in user1 present in user2, should copied if somemodel belongsto user, every instance of somemodel pointing user2 should modified point user1 same if somemodel hasandbelongstomany user if somemodel hasmany user, , somemodel1 has user2 no other instance has user1, should modified somemodel1 has user1 instead if somemodel hasmany user, somemodel1 has user1 , somemodel2 has user2... well, i'm not sure here, guess solution discard somemodel2, since user1 can belongto 1 somemodel. finally user2 should removed. is there way automate this? maybe behaviour? if not, may consider creating it, since need lot. we made merge behaviour purpose in 2008. it may require tweaking work correctly latest cakephp stable release can find here

let's say, example, flash file loaded. while loading, retrieves data xml file. if wanted change value in xml, automatically change in glash? if not? there method in actionscript allow change occur instantly after xml file changed? when flash loads in xml file, it's downloading data - it's one-time transaction. if change file, flash retains version downloaded unless tell download again. it sounds want bit more dynamic simple xml config file, right? there ways make flash interact directly server, without using xml dump intermediary. depending on need, might consider looking amfphp flash remoting - allows flash call methods directly on server, , passes typed objects. this, depending on data you're passing around implement server polling flash calls server once every few seconds see if there's new data, or effect? alternately, if need tighter information flow between server , flash might consider setting socket connection. google flash's native so...

this extract advanced liniux programming: semaphores continue exist after processes using them have terminated. last process use semaphore set must explicitly remove ensure operating system not run out of semaphores.to so, invoke semctl semaphore identifier, number of semaphores in set, ipc_rmid third argument, , union semun value fourth argument (which ignored).the effective user id of calling process must match of semaphore’s allocator (or caller must root). unlike shared memory segments, removing semaphore set causes linux deallocate immediately. if process allocate shared memory, , many process use , never set delete (with shmctl), if them terminate, shared page continues being available. (we can see ipcs). if process did shmctl, when last process deattached, system deallocate shared memory. so far (i guess, if not, correct me). what dont understand quote did, first say: "semaphores continue exist after processes using them have terminated." , then: ...

on embedded platform (with no swap partition), have application main process occupies of available physical memory. problem want launch external shell script application, using fork() requires there enough memory 2x original process before child process (which execl smaller) can created. so there way invoke shell script c program without incurring memory overhead of fork()? i've considered workarounds such having secondary smaller process responsible creating shells, or having "watcher" script signal touching file or somesuch, i'd rather have simpler. some unix implementations give vfork (part of single unix spec) fork except shares stuff parent. with vfork , there limited number of things can in child before calling exec overwrite address space process - that's vfork built for, minimal copy version of fork fork/exec sequence.
