<title>소개</title>
<para>
시스템 콜이란 리눅스 커널에 의해 제공되는 서비스이다. 예를 들어
파일에 쓰는 서비스를 이용하길 원한다면 프로그래머는 리눅스에서
제공하는 해당 시스템콜을 이용해서 프로그램을 작성한다.
C를 이용해서 프로그래밍을 할경우 대부분의 시스템콜은 libc를 통한
포장(wrapper)함수형태로 제공받을 수 있다.
</para>
<para>
시스템 콜 함수에 대한 정보는 메뉴얼 페이지(man page)의 섹션 2번을
통해서 얻어올 수 있다. 예를 들어 read()시스템콜에 대한 정보를 얻기를
원한다면 man 2 read 하면 된다. 시스템콜에 대한 소개를 원한다면
<emphasis>man 2 intro</emphasis>를 이용하기 바란다.
<screen>
# man 2 intro
</screen>
</para>
<para>
시스템 콜을 사용하기 위해서 libc를 통한 포장함수를 호출하는 외에도
syscall()함수를 이용해서 직접 실행시키는 방법도 있다. 각각의
시스템콜은 고유한 번호를 가지고 있는데, syscall에 이 시스템 콜의
번호를 입력하는 방식으로 호출한다. 내부적으로 syscall은 0x80 인터럽트를
이용해서 커널에 명령을 전달한다.
</para>
<para>
시스템 콜함수들은 syscall.h 와 unistd.h 에 정의되어 있으며,
시스템 콜 테이블은 "arch/i386/kernel/entry.S"리눅스 커널 소스파일에
정의되어 있다.
