shared

问题 I am trying to implement shared memory on embedded device with uClinux. My C source #include <stdio.h> #include <sys/shm.h> #include <sys/stat.h> #include <sys/socket.h> #include <errno.h> //using namespace std; int main() { int segment_id; segment_id = shmget(04, getpagesize(), IPC_CREAT | 0666); printf("Page size - %d\n",getpagesize()); printf("Error in socket - %d\n",errno); } I get an error Page size - 4096 Error in socket - 38 Can anyone help me? Thanks. 回答1: You need to test segment_id

问题 Assume my platform is vanilla (non-embedded) x86-64 Linux using GNU build toolchain (GCC, etc.). To specify $ORIGIN in RPATH , I know about the linker option: -Wl,-rpath,'\$\$ORIGIN' . Today, I discovered another option: -Wl,-z,origin . Should I always include -Wl,-z,origin when using -Wl,-rpath,'\$\$ORIGIN' ? Official GNU ld docs, say: Marks the object may contain $ORIGIN. Related, but different: https://stackoverflow.com/questions/33853271/what-are-the-recommended-gnu-linker-options-to

问题 I'm trying to do a parallel reduction to sum an array in CUDA. Currently i pass an array in which to store the sum of the elements in each block. This is my code: #include <cstdlib> #include <iostream> #include <cuda.h> #include <cuda_runtime_api.h> #include <helper_cuda.h> #include <host_config.h> #define THREADS_PER_BLOCK 256 #define CUDA_ERROR_CHECK(ans) { gpuAssert((ans), __FILE__, __LINE__); } using namespace std; inline void gpuAssert(cudaError_t code, char *file, int line, bool abort

问题 I want to bind icons to the MenuItem controls where these items are dynamically created. I tried to set the x:Shared attribute to False but always only the last item has icon. Here is my style for the MenuItems ItemContainerStyle code: <Window.Resources> <Style TargetType="{x:Type MenuItem}" x:Key="MenuItemStyle" x:Shared="False"> <Setter Property="Icon"> <Setter.Value> <Image Source="{Binding IconSource}" /> </Setter.Value> </Setter> </Style> </Window.Resources> And the MenuItem definition:

问题 I am reading the Rust 101 tutorial, where the author talks about shared borrowing with the example of a Vec object passed to a function. Below is a slightly adapted MWE of what the the tutorial is teaching. The interesting part is v.iter() in vec_min . The author writes: This time, we explicitly request an iterator for the vector v . The method iter borrows the vector it works on, and provides shared borrows of the elements. But what happens if I use a for ... in ... construction on an object

问题 I have created a server side application in PHP that's supposed to work with Google Spreadsheets. I'm able to authenticate successfully with OAuth 2.0 authentication, but when requesting the list of the spreadsheets from Google, I only get the spreadsheets shared with the service account by the spreadsheet owner. Is there a way that service account could retrieve all the spreadsheets owned by my main account not the service one, including those not explicitly shared with the service account?

Improve this question I am working on a VBA that access a shared excel file to check if the file is used by someone else or not. By that time VBA should not allow other users to access the file in edit mode they should open it in read-only mode if they already opened the file as well. Basically,

问题 I've install a program in Centos 6.8, While running the program, I receive error "error while loading shared libraries: libm.so.6: cannot open shared object file: No such file or directory" when I checked the linked library to the program using ldd command, I can see libm.so.6 with correct 64bit "libm.so.6 => /lib64/libm.so.6 (0x0000003a19000000)" That means, library is installed and already added in environment variable, LD_LIBRARY_PATH Another program, which uses libm.so.6, works fine.
