multithreading - how can I use multi-threading in a c++ application on a mac? -


i need add threading code below, whats quick way so?

int main() {     objecttype obj1;     objecttype obj2;     printmaze(obj1, obj2);     getuserinput(obj1, obj2);     return 0; }  void printmaze(objecttype&obj1, objecttype&obj2){     ///     ///     /// }  void getuserinput(objecttype&obj1, objecttype&obj2){     ///     ///     /// }

i want able call printmaze , getuserinput in separate threads , have them use same variables [in essence share variable].

just off top of head, quick way implement threads on mac

#include <stdio.h> #include <time.h> #include <pthread.h> #include <stdio.h> #include <stdlib.h>  //contains information needed struct allinfo{     objecttype obj1;     objecttype obj2; };  int main() {     srand(time(null));     pthread_t printingthread;     pthread_t inputthread;     allinfo info;     pthread_create(&printingthread, null, &printmaze, &info);     pthread_create(&inputthread, null, &getuserinput, &info);     pthread_exit(null);     return 0; } void *printmaze(void * infoarg) {     allinfo *info;     info= ( allinfo *)infoarg;     ///     ///     pthread_exit(null); } void *getuserinput(void *infoarg) {     allinfo *info;     info= (struct allinfo *)infoarg;;     ////     ////     pthread_exit(null); }

you'll notice couple of things when passing arguments function called in thread,
[1] can pass 1 argument function if need more 1 argument in function call, have bundle separate arguments using struct. and
[2]when passing arguments function being called in thread, need first accept function object of type "void *" before typecasting original "allinfo" objecttype.

How to understand 2 main() functions after using uftrace to profile the C++ program? -

i trying uftrace profile following simple c++ program: #include <iostream> class { public: a() {std::cout << "a created" << std::endl;} ~a() {std::cout << "a destroyed" << std::endl;} }; int main() { a; return 0; } the profile result this: # uftrace a.out created destroyed # duration tid function 2.026 [ 4828] | __cxa_atexit(); [ 4828] | main() { [ 4828] | __static_initialization_and_destruction_0() { 89.397 [ 4828] | std::ios_base::init::init(); 0.768 [ 4828] | __cxa_atexit(); 93.029 [ 4828] | } /* __static_initialization_and_destruction_0 */ 94.425 [ 4828] | } /* main */ [ 4828] | main() { [ 4828] | a::a() { 11.104 [ 4828] | std::operator <<(); 10.825 [ 4828] | std::basic_ostream::operator <<(); 24.514 [ 4828] | } /* a::a */ [ 4828] | a::~a() { 0.978 [ 4828] | ...
