今天，我们聊一聊 malloc 函数在单片机程序设计中怎么使用。 最近更新 RT-Thread 专栏到了内存管理的时候，想了想该怎么来说明这个内存管理，实际上在平时使用STM32做一般产品的时候基本不会用到 malloc 函数，即便是使用了操作系统，在业务逻辑不复杂的情况下 ...

这个问题看起来十分刁钻，不过稍有常识的人都知道，制定 C 标准的那帮语言律师也不是吃白饭的，对这种奇奇怪怪的问题一定会有定义。 我们翻阅 C17 标准 草案 N2176，在 7.22.3 节里，有如下说法： The order and contiguity of storage allocated by successive calls to the aligned ...

A topic that I find particularly interesting, which is raised by many embedded software developers whom I meet, is dynamic memory allocation – grabbing chunks of memory as and when you need them. This ...

Memory is required to run programs on your computer. Of course, the program itself needs to be loaded into memory, and it is no exaggeration to say that most of the operations performed by the program ...

Hi,<BR><BR>I've been having some difficulty with a C assignment that I have (I'm starting to realize how much PHP and Java spoils me!). Its a simple cash register that asks for the type of purchase, ...

In C and C++, it can be very convenient to allocate and de-allocate blocks of memory as and when needed. This is certainly standard practice in both languages and almost unavoidable in C++. However, ...

Dealing with dynamic memory traditionally has been one of the most awkward issues of C and C++ programming. It is not surprising that some supposedly easier languages, such as Java, have introduced ...
