D3D11_MAP枚举值类型的成员如下: 最后映射出来的内存我们可以通过memcpy_s函数来更新。 默认情况下,若待访问资源仍在被GPU使用,CPU会阻塞直到能够访问该资源。 注意:千万不要对只支持写操作的映射内存区域进行读取操作!否则这会招致十分显著的性能损失。即便是像这样的C++代码:*((int*)MappedResource.pData) = 0...
后者主要在你想明确控制截断的时候使用; 如果不想明确控制截断, 则首选前者。 2. 不要使用不安全的C运行库字符串处理函数。 一般情况下,你使用或实现的任何缓冲区处理例程都必须获取目标缓冲区的长度作为一个参数。 C 运行库提供了一系列缓冲区处理替代函数,比如 memcpy_s,memmove_s,wmemcpy_s或wmemmove_s。 ...
