Loading pid_t into an array for use OUTSIDE of forked process C/linux -


i have have application forks quite few child processes. store these child pid's in array when max_child reached. can kill off oldest ones.

any way of accomplishing ?

note... in real application fork , not wait process finish

here test snippet...

---main

 pid_t pid;      if ((pid = fork()) < 0) {         printf("[*]- error -> fork returned -1\n\n");     }      else if (pid == 0) {         // success         // child process begins here         printf("inside child @ pid %i . check ps\n", pid);         sleep(30);     }      else {         // still here         // maybe store pid global array here?         printf("back parent pid: %i child: %i\n\n", getpid(), pid);     }      // pid comes out 0 here expected     printf("pid: %i\n", pid);

so store pid int array maybe? how correctly cast pid_t? want able call cleanup() function , have step through list of child pids see if still active, if yes, kill oldest.

any advice appreciated. thank you.

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...
