我试图将2个无符号整数传递给C中新创建的线程(使用pthread_create())但是也没有2个整数或结构的数组似乎有效.
// In my socket file
struct dimension {
unsigned int width;
unsigned int height;
};
unsigned int width, height;
void setUpSocket(void* dimension) {
struct dimension* dim = (struct dimension*) dimension;
width = dim->width;
height = dim->height;
printf("\n\nWidth: %d, Height: %d\n\n", width, height);
}
// In main.cpp
// Pass a struct in pthread_create
struct dimension dim;
dim.width = w;
dim.height = h;
pthread_create(&ph, &attr, (void * (*)(void *)) setUpSocket, (void *) &dim);

在调用pthread_create之前,dim.width和dim.height是正确的.在我的套接字文件中,只设置了宽度,高度为0,我不明白为什么.
有谁知道什么是错的,请问如何解决?
非常感谢你.
