laClinux內存管理采用非標準Linux內存模型。系統為進程分配連續內存區域,代碼段、數據段和棧段間無空隙,且進程私有堆被取消,所有進程共享由操作系統管理的堆空間。最簡單的malloc利用mmap從核心空閑內存池中分配內存以實現。并采用存儲器分頁管理,系統啟動時把實際存儲器分頁,加載應用程序時再程序分頁加載

UART I/O and Memory Allocation Example for GNU The project GNU_IODemo shows how to use memory allocation routines (malloc) and char I/O (printf, scanf) via a serial interface with the GNU toolchain. The I/O functions are adapted for the Analog Devices ADuC7000 series using the SERIAL.C module. The example also shows the efficiency of the Keil CA ARM Compiler run-time library which is tuned for single chip systems.

This code detects memory leaks in embedded VC++ almost the same way crtdbg does in VC++. At the end of program execution it will display in the debug window if there were any memory leaks and how the memory looks so you can identify where your memory leak occurred. It will display in the debug window a message saying no memory leaks detected if there are no memory leaks. Similar to what crtdbg.h does in VC++. The code detects memory leaks generated with calls to new and delete operators in C++. The code doesn t detect memory leaks generated with C functions: malloc, calloc, free, but that can be done in the future. Let me know and I will program it.

* Function: * 1. Replace the first oldstr with newstr in srcstr * Arguments: * IN : * srcstr * oldstr * newstr * OUT : * srcstr * Return: * 1. If find and replace one oldstr with newstr in srcstr , return 1 * 2. If find no oldstr in srcstr , return 0 * 3. If error (malloc return NULL) return -1 * Notes: * 1. srcstr should be large size enough.

實習題 [問題描述] 1. 設順序表中的數據元素遞增有序,將插入到順序表的適當位置上,是該表仍然有序。 [輸入] 初始順序表,插入字符。 [輸出] 插入x后線性表的結果 [存儲結構] 采用順序存儲結構 [算法的基本思想] 建立一個遞增順序表,插入一個數值并移動元素,使其仍然有序。 程序如下: #include "iostream.h" #include <malloc.h> #define LIST_INTI_SIZE 100//初始空間大小 typedef struct SqList

1.[問題描述] 編寫遞歸算法,計算二叉樹中葉子結點的數目 [輸入] 按照先序序列的順序輸入該結點的內容。其輸入abd eh cf i g . [輸出] 按中序序列輸出,輸出的結果為;dbheaficg并計算出二叉樹中葉子結點的數目為4 [存儲結構] 采用二叉表存儲 [算法的基本思想] 采用遞歸方法建立和遍歷二叉樹。首先建立二叉樹的根結點,然后建立其左右子樹,直到空子樹為止,中序遍歷二叉樹時,先遍厲左子樹,后遍厲右子樹,最后訪問根結點。根據左右子樹的最后一個結點計算出二叉樹中葉子結點的數目。 程序如下: #include<stdio.h> #include<malloc.h> #include"stdlib.h"
