RMI$_MODES

RMI$_MODES returns the amount of time, in 10-ms units, spent by all currently active CPUs in all processor modes since the system was booted. Each increment in the returned time for a mode represents an additional 10 ms spent by the CPU in that mode. An active CPU is one that is actively participating in the processor scheduling that the OpenVMS instance performs.

The buffer length field in the item descriptor is dependent on the number of CPUs attached to the system. The size of the buffer passed should be as follows:

     n * sizeof ( CPU_struct ) + 4 

where n is the available CPU count. Use $GETSYI item code SYI$_POTENTIALCPU_CNT to get n, the count of potentially available CPUs. (For details, see the description of the $GETSYI service.)

Data for an individual CPU is returned by means of a CPU_struct structure. Declare the CPU_struct with no member alignment, as in the following example:

#pragma member_alignment save 
#pragma _nomember_alignment 
typedef struct _CPU_struct 
{ 
    unsigned char   cpu_id;     // physical cpu id 
    unsigned int    interrupt;  // is actually the sum of interrupt and idle1
    unsigned int    mpsynch;    // multi-processor synchronization 
    unsigned int    kernel;     // kernel mode 
    unsigned int    exec;       // executive mode 
    unsigned int    super;      // supervisor mode 
    unsigned int    user;       // user mode 
    unsigned int    reserved;   // reserved, will be zero 
    unsigned int    idle;       // CPU idle 
}CPU_struct; 
#pragma member_alignment restore 

For a multiple-CPU system, the data for all active CPUs is returned as an array of type CPU_struct, with the number of elements in the array equal to the number of potentially available CPUs. If a CPU is inactive, the CPU_struct array element corresponding to that CPU contains 0 in all CPU_struct members.

Be sure to allocate a buffer large enough to hold the counters for all available CPUs.

The following code example shows one method for collecting CPU modes:

#include <starlet.h> 
#include <syidef.h> 
#include <rmidef.h> 
#include <efndef.h> 
#include <iledef.h> 
#include <iosbdef.h> 
 
CPU_struct   *cpu_counters = NULL; 
IOSB          myiosb = { 0 }; 
char         *buffer; 
unsigned long buffer_size; 
int           status; 
 
// Set up the $GETSYI item list: potential CPUs and active CPU bitmask 
// unsigned long 
CPU_Count = 0; 
unsigned long long ActiveCPUs = 0; 
 
ILE3 SYIitmlst[] = { {sizeof CPU_Count, SYI$_POTENTIALCPU_CNT, &CPU_Count, 0}, 
                     {sizeof ActiveCPUs, SYI$_ACTIVE_CPU_MASK, &ActiveCPUs, 0}, 
                     {0,0}}; 
 
// Get the available CPU count and a bitmask of active CPUs 
status = SYS$GETSYIW( EFN$C_ENF, NULL, NULL, SYIitmlst, &myiosb, NULL, 0 ); 
buffer_size = CPU_Count * sizeof( CPU_struct ) + 4; 
buffer = malloc( buffer_size ); 
 
// Set up the $GETRMI item list: CPU modes 
ILE3 RMIitmlst[] = {{buffer_size, RMI$_MODES, buffer, 0}, 
                    {0,0}}; 
 
// Call the service 
status = SYS$GETRMI( EFN$C_ENF, 0, 0, RMIitmlst, &myiosb, NULL, 0 ); 
   .
   .
   .
status = SYS$SYNCH 
   .
   .
   .
// THE DATA COUNTERS BEGIN 4 BYTES OFF THE START OF THE BUFFER; 
// The first 4 bytes of the buffer are reserved for internal use. 
cpu_counters = (CPU_struct *) ( buffer + 4 ); 
 
// Use the counters for all active CPUs 
for ( int i = 0; i < CPU_Count; i++) 
{ 
    if ( 1 == ( 1 & (ActiveCPUs >> i) ) ) 
    { 
       cpu_counters[i].interrupt 
       --- 
       --- 
       --- 
    } 
} 
 
free( buffer );
