C++ (Cpp) sys_sched_rr_get_interval Examples

Example #1

/* Note: it is necessary to treat pid as an unsigned int, 
 * with the corresponding cast to a signed int to insure that the 
 * proper conversion (sign extension) between the register representation of a signed int (msr in 32-bit mode)
 * and the register representation of a signed int (msr in 64-bit mode) is performed.
