AI代码解释 intcheck_sys(){int i=1;return(*(char*)&i);}intmain(){int ret=check_sys();if(ret==1){printf("小端\n");}else{printf("大端\n");}return0;} 在函数check_sys()中,定义了一个整型变量i并初始化为1。 然后使用类型转换,将i的地址强制转换为char类型的指针,并通过解引用操作符*...
1 前言 XS是Perl与C的胶水语言,通过它能在Perl中创建方法,以此扩展C库中的函数或新定义的C函数,详情可参阅《官方手册:perlxs》。 XS的编译器叫做xsubpp,它用typemaps去决定如何映射C函数的参量和输出值到Perl的值中并返回。“XSUB结构(XSUB forms)”是XS接口的基本单元,一个XSUB被编译后等效于一个C函数,其...
