Linux C++ - IP地址轉換函數

1.

函數用途：數字網絡序本地序轉換

適用類型：IP地址uint32_t類型、端口號uint16_t類型

#include<netinet/in.h>
extern uint32_t ntohl (uint32_t __netlong) __THROW __attribute__ ((__const__));
extern uint16_t ntohs (uint16_t __netshort) __THROW __attribute__ ((__const__));
extern uint32_t htonl (uint32_t __hostlong) __THROW __attribute__ ((__const__));
extern uint16_t htons (uint16_t __hostshort) __THROW __attribute__ ((__const__));

2.

函數用途：點分十進制IP地址的字符串轉換為網絡序二進制數

適用類型：XXX.XXX.XXX.XXX轉uint32_t類型

#include<apra/inet.h>
extern in_addr_t inet_addr (const char *__cp) __THROW;

extern int inet_aton (const char *__cp, struct in_addr *__inp) __THROW;

extern char *inet_nsap_ntoa (int __len, const unsigned char *__cp, char *__buf) __THROW;
