返回类型：char

参数：

类型参数名称
char *buf
char *end
const void *ptr
struct printf_specspec
793  str等于如果ptr的长度恒等于8则"(____ptrval____)"否则"(ptrval)"
798  如果此条件成立可能性小(为编译器优化)(Make pointers available for printing early in the boot sequence. )则
799  hashval等于hash_long((unsignedlong)ptr, 32)
800  返回:pointer_string(buf, end, (constvoid * )hashval, spec)
803  ret等于Maps a pointer to a 32 bit unique identifier.
804  如果ret则
805  width of output field 等于2乘ptr的长度
807  返回:Be careful: error messages must fit into the given buffer.
810  返回:pointer_string(buf, end, (constvoid * )hashval, spec)
