Sorry for my unclear words...
I want to know the DIFFERENCE between SYSCALL() and _SYSCALLN()...
_syscallN() ( _syscall0(),_syscall1(),...._syscall6() ) is a macro defined
in include/asm/unist.h while syscall() is a glibc function which I'm not
sure. Thanks!

This is described in the manual page for syscalss

~: man syscalls

.... 164 system calls.. depending on your kernel version.. etc..

Roughly speaking, the code  belonging  to  the  system  call  with  number
__NR_xxx  defined  in /usr/include/asm/unistd.h can be found in the kernel
source in the routine sys_xxx().  ...... etc...
