如何将布尔运算符==添加到结构bd_addr_t
?我在C++项目中使用这个文件。bool operator == typedef struct
#ifndef APITYPES_H_
#define APITYPES_H_
#ifdef __GNUC__
#define PACKSTRUCT(decl) decl __attribute__((__packed__))
#define ALIGNED __attribute__((aligned(0x4)))
#else //msvc
#define PACKSTRUCT(decl) __pragma(pack(push, 1)) decl __pragma(pack(pop))
#define ALIGNED
#endif
typedef unsigned char uint8;
typedef unsigned short uint16;
typedef signed short int16;
typedef unsigned long uint32;
typedef signed char int8;
typedef struct bd_addr_t
{
uint8 addr[6];
}bd_addr;
typedef bd_addr hwaddr;
typedef struct
{
uint8 len;
uint8 data[];
}uint8array;
typedef struct
{
uint8 len;
int8 data[];
}string;
#endif
我尝试添加
bool operator==(const bd_addr_t& a) const
{
return (addr[0] == a.addr[0] && addr[1] == a.addr[1] && addr[2] == a.addr[2] && addr[3] == a.addr[3] && addr[4] == a.addr[4] && addr[5] == a.addr[5]);
}
但是,这将引发编译过程中两个错误:
unknown type name 'bool' bool operator==(const bd_addr_t& a) const
expected ':', ',', ';', '}' or '__attribute__' before '==' token bool operator==(const bd_addr_t& a) const
你有没有审查[比较运算符](http://en.cppreference.com/w/cpp /语言/ operator_comparison)? –
你真的在这个文件上使用C++编译器吗?看起来它不知道典型的C++特性。 – bipll
为什么在C++中使用'typedef struct'? – Slava
