sizeof(whar_t) = 4 用mbstowcs转换后结果不对,看了下android 源码 size_t mbsrtowcs(wchar_t *dst, const char **src, size_t len, mbstate_t *ps) { const char* s = *src; const char* s2 = memchr( s, 0, len ); if (s2 != NULL) len = (size_t)(s2 - s) + 1U; if (dst)...
http://code.opencv.org/issues/4262 在Mat类型在OpenCV-java的使用方式和在C++中的使用方式不同,在C++中Mat是系统自动管理内存垃圾回收,而在Java中需要通过Mat.release;方法手动释放内存否则会出现标题错误

voidbzero(void*,size_t); I've seen other people having trouble with this type of line because size_t is the wrong value. Some have fixed it by replacing size_t with the kernel's definition. My guess is that the order in which I'm including things is clobbering some definition that ...
AMotionEvent_getPointerId(const AInputEvent* motion_event, size_t pointer_index);不知道怎么用 AMotionEvent_getRawX(event,0);//这个返回的是相对于屏幕左上角的坐标, AMotionEvent_getX(event,0);//和AMotionEvent_getRawX返回值一样 //这两个函数,如果第二个参数改成1之后,返回值总是为0.0 ...
Linux版: malloc（配置内存空间） 相关函数 calloc，free，realloc，brk 表头文件 #include 定义函数 void * malloc(size_t size); 函数说明 malloc()用来配置内存空间，其大小由指定的size决定。 返回值 若配置成功则返回一指针，失败则返回NUL...
