kernel_types.h

它通过提供glibc兼容使得应用程序移植到较小的c 库时相当得容易. 它能够应用到带虚拟存储的Linux和uClinux上.在大多数带MMU部件的平台上为使它更加紧凑,它也能够编译成共享库.uClib

/* Note that we use the exact same include guard #define names
 * as asm/posix_types.h.  This will avoid gratuitous conflicts 
 * with the posix_types.h kernel header, and will ensure that 
 * our private content, and not the kernel header, will win.
