无、p:如果定义了std::uintptr_t,那么如同通过调用std::to_chars(first, last,reinterpret_cast<std::uintptr_t>(value),16)产生输出,并添加前缀0x到输出;否则输出由实现定义。 P:与p相同,但 9 以上的数位会以大写字母表示,并且底前缀变为0X。

is treated as a typedef name:intf(size_t,uintptr_t)is parsed as a new-style declarator for a function taking two unnamed parameters of type size_t and uintptr_t, not an old-style declarator that begins the definition of a function taking two parameters named "size_t" and "uintptr_t...
The critical section is larger than the one line you showed me on slack. Having said that, I don't see what we are trying to protect, except for that comp()->fej9()->getObjectClassAt((uintptr_t)stringConst); line. So the change looks good to me....

没有指向函数指针和指向对象指针(含 void*)间的转换 若实现提供 intptr_t 与/或 uintptr_t,则从指向对象类型(包括 cv void)的指针转换为这些类型始终良定义。然而这对于函数指针并不保证。 (C99 起)注意函数指针与对象指针间的转换被许多编译器作为扩展接受,并且为 POSIX dlsym() 函数的一些用法所期待。 示...
