```c #include <arpa/inet.h> int inet_pton(int af, const char *src, void *dst); ``` 其中,af是地址族,可以是AF_INET(IPv4)或AF_INET6(IPv6);src是要转换的点分十进制格式的IP地址;dst是用于存储转换结果的缓冲区。 inet_pton函数的返回值为整型,如果转换成功,返回1(IPv4)或2(IPv6);如果转...
【C】volatile07-30 收起 1、inet_pton #include <arpa/inet.h> int inet_pton(int af, const char *restrict src, void *restrict dst); 将IPv4和IPv6地址从文本转为二进制。(网络字节序) af参数有以下取值: AF_INET src指向ipv4地址文本,格式ddd.ddd.ddd.ddd。地址会被转化为struct in_addr,...
原型:int inet_pton( int family, const char *strptr, void *addrptr ); 功能:将字符串strptr(即表达格式的地址)转换为网络地址。 参数:family既可以是AF_INET,也可以是AF_INET6; strptr指向ASCII地址的首地址(***.***.***.***格式),addrptr是套接字地址结构; 返回值: 如果成功返回1; 如果函数出...
