Linux中的“ sys / ioctl.h”标头
我在 Linux 2.6.32-26-generic 当我查看“ ioctl.h”听众文件的linux源代码时,我可以看到许多变体。(对于不同的平台,我想)。即 ./fs/ocfs2/ioctl.h ./fs/btrfs/ioctl.h ./fs/ceph/ioctl.h ./include/config/i2o/config/old/ioctl.h ./include/asm-generic/ioctl.h ./include/linux/hdlc/ioctl.h ./include/linux/ioctl.h ./drivers/video/via/ioctl.h ./drivers/staging/vt6655/ioctl.h ./drivers/staging/vt6656/ioctl.h ./arch/ia64/include/asm/ioctl.h ./arch/h8300/include/asm/ioctl.h ./arch/microblaze/include/asm/ioctl.h ./arch/score/include/asm/ioctl.h ./arch/avr32/include/asm/ioctl.h ./arch/alpha/include/asm/ioctl.h ./arch/x86/include/asm/ioctl.h ./arch/m32r/include/asm/ioctl.h ./arch/mn10300/include/asm/ioctl.h ./arch/sparc/include/asm/ioctl.h ./arch/powerpc/include/asm/ioctl.h ./arch/m68k/include/asm/ioctl.h ./arch/sh/include/asm/ioctl.h ./arch/xtensa/include/asm/ioctl.h ./arch/mips/include/asm/ioctl.h ./arch/s390/include/asm/ioctl.h ./arch/arm/include/asm/ioctl.h ./arch/blackfin/include/asm/ioctl.h ./arch/frv/include/asm/ioctl.h ./arch/parisc/include/asm/ioctl.h ./arch/cris/include/asm/ioctl.h 但我看到该文件被包含为 #include <sys/ioctl.h> 此映射如何工作?
