C语言学习day23：WriteProcessMemory函数/游戏内存数据修改工具开发上一章我们说了获取应用进程的某数据（data），这一章我们就说说修改内存地址的数据。想要修改内存，那么就需要我们另一个WinAPI函数：WriteProcessMemory()函数。阅读详情





int abc = 50;

void mytest2()

{

	int add;

	add = (int)&abc;

	//若不用WriteProcessMemory方法，可以操作add这个地址，改写abc的值吗？

}

3D-IC测试挑战与Tessent解决方案解析 3D-IC技术通过硅通孔(TSV)实现芯片垂直堆叠，是延续摩尔定律的关键路径。该技术面临三大核心挑战：KGD标准严苛化要求测试覆盖率达99.5%以上，存储器测试需兼容LPDDR/HBM等多种协议，逻辑堆叠需解决TSV互连的电气特性和时序验证问题。Mentor Tessent平台采用混合测试架构，结合压缩扫描测试(ATPG)和内建自测试(BIST)技术，实现100x测试数据压缩比和99.97%的TSV缺陷检出率。这些创新方案在移动SoC和高性能计算芯片中已获验证，测试时间缩短73%，缺陷逃逸率降低77%。随着阅读详情

谢谢各位，刚接触指针，还不会活学活用

IsBadWritePtr The IsBadWritePtr function verifies that the calling process has write access to the specified range of memory. BOOL IsBadWritePtr( LPVOID lp, // address of memory block UINT ucb // size of block ); Parameters lp Pointer to the first byte of the memory block. ucb Specifies the size, in bytes, of the memory block. If this parameter is zero, the return value is zero. Return Values If the calling process has write access to all bytes in the specified memory range, the return value is zero. If the calling process does not have write access to all bytes in the specified memory range, the return value is nonzero. To get extended error information, call GetLastError. If the application is compiled as a debugging version, and the process does not have write access to all bytes in the specified memory range, the function causes an assertion and breaks into the debugger. Leaving the debugger, the function continues as usual, and returns a nonzero value This behavior is by design, as a debugging aid. Remarks If the calling process has write access to some, but not all, of the bytes in the specified memory range, the return value is nonzero. In a preemptive multitasking environment, it is possible for some other thread to change the process's access to the memory being tested. Even when the function indicates that the process has write access to the specified memory, you should use structured exception handling when attempting to access the memory. Use of structured exception handling enables the system to notify the process if an access violation exception occurs, giving the process an opportunity to handle the exception. QuickInfo Windows NT: Requires version 3.1 or later. Windows: Requires Windows 95 or later. Windows CE: Requires version 1.0 or later. Header: Declared in winbase.h. Import Library: Use kernel32.lib.

int abc = 50; void main() { int *add = &abc; *add = 20; }

不知道lz怎么学的，这不是基本的基本么。

int a = 0;
int* b = &a;
*b = 1;

*add = 20; 这样编译器会报错，无法直接操作内存地址
