Is there any standardized function in GCC or glibc to allocate memory block at aligned po开发者_如何学编程inter?
I thought I understood how C/C++ handled struct member alignment. But I\'m getting strange results for a particular arrangement in Visual Studio 2008 and 2010.
I heard a lot that data should be properly aligned in memory for better access efficiency. CPU access memory on a word boundary.
How will gcc set the alignment for variable/field with __attribute__((aligned)) What about different gcc versions/ different platforms?
You can allocate a std::vector which allocates aligned heap memory by defining your own allocator. You can allocate a c-style array on the stack using declspec align.开发者_运维百科
I have some software that I have working on a redhat system with icc and it is working fine. When I ported the code to an IRIX system running with MIPS then I get some calculations that come out as \"
I have understood why memory should be aligned to 4 byte and 8 byte based on data width of the bus. But following statement confuses me
I\'ve run into a EXC_BAD_ACCESS with a piece of code that deals with data serialization. The code only fails on device (iPhone) and not on simulator. It also fails only on certain data types.
Let have a type T and a struct having ONLY uniform elements of T type. struct Foo { T one, T two, T three
Suppose this code: unsigned char list[3] = { 1, 2, 3 }; struct _struct{ unsigned char a; unsigned char b;
