/*\
* [Description]
* This test case checks whether reboot(2) system call returns appropriate
* error number for invalid flag parameter or invalid user.
*
* [Algorithm]
* Execute system call with invaid flag parameter and then for invalid user
* check return value and errno.
*
* [Restrictions]
* For lib4 and lib5 reboot(2) system call is implemented as
* int reboot(int magic, int magic2, int flag, void *arg); This test case
* is written for int reboot(int flag); which is implemented under glibc
* Therefore this testcase may not work under libc4 and libc5 libraries
