2.6.X中，已经取消了宏_syscallN的定义，如果想要调用自己添加的系统函数怎么声明？

_syscall2(int,mycopy,const char *,s_file,const char *,t_file) 应该修改成什么？？

有些说法是 int syscall(5,mycopy,const char *,s_file,const char *,t_file)??

但是有报错信息：
Compiler executable checksum: 92efef273c2911dfe2bff20f05a618b3
mycopy.c:13: 错误：expected declaration specifiers or ‘...’ before numeric constant
