Linux/システムコール
http://linux.die.net/man/2/syscalls
メモ
- システムコールは一般には直接起動されず、 glibc (や他の何らかのライブラリ) 経由で起動される
Linuxカーネル
- sys_?システムコール名という関数で実装されている
- linux/syscalls.h
定義
- SYSCALL_DEFINE
- 後ろの数字はシステムコールの引数の数
- 通常の関数定義では変数の型と変数名の間に゛,”はありませんが、SYSCALL_DEFINEでは型と変数名の間に゛,”をつけて区切ります。
番号の定義
- arch/x86/include/asm/unistd_32.h
- arch/x86/include/asm/unistd_64.h?
- uapi/asm-generic/unistd.h?
関数との対応表
- arch/x86/kernel/syscall_table_32.S?
