The so-called descriptor, to some extent, is equivalent to a string. Just unlike C + + strings, the descriptors in Symbian describe their length with an additional integer, rather than a ' yes ' terminator. Thus, descriptors can express arbitrary

Introduction to DMA and Direct Memory Access for STM32, dmastm32 The first time I came into contact with DMA, I learned the arm9-bare-board program at school. I thought it was almost two years later. Now let's take a look at the dma of the STM32

Interview tips for C and C ++ programmers and interview tips for programmers Many advanced languages use C/C ++ for reference. Therefore, the C/C ++ language is very important for software developers.  The interview tips for C and C ++ programmers

  Sometimes some data in the program needs to be permanently saved or called globally for other reasons, but the global data is dangerous for development. Static is introduced here, which is very useful.   I understand static as follows:   When an

The following code is available:1#include 2 intA =3;3 Const intD4;4 5 Main ()6 {7 intstate[2*A];//Error8 9 intTST[B];//ErrorTen}The above two array declaration statements are all wrong, because the array length requirement is

ITEM4 to ensure that objects are initialized before they are usedC + + is mutable on object initialization, such as the following example:Int x;In some contexts, X is guaranteed to be initialized to 0, and in some other cases it cannot be guaranteed.
