function that returns memory size?

[douglaskbell]

I'm fixing a memory leak, and need a function that returns the present available heap size, or heap usage.

We tried getrusage() but it returns 0's............thus:

maximum resident set size 0
integral shared memory size 0
integral unshared data size 0
integral unshared stack size 0
page reclaims 0
page faults 0
swaps 0
block input operations 0
block output operations 2
messages sent 0
messages received 0
signals received 0
voluntary context switches 2
involuntary context switches 1

Please show the code you used, including variable declarations, #include files, etc.

BTW, it's running on SunOS 5.9

And, I need to programatically read the same 'size' that 'top' returns.

int Error;
struct sysinfo Resource_Metrics;

Error = sysinfo( &Resource_Metrics );
if( !Error )
{
printf("\n print_memory_usage.............. ");


printf("\n Seconds since boot %ld", Resource_Metrics.uptime );
printf("\n Total usable main memory size %ld", Resource_Metrics.totalram );
printf("\n Available memory size %ld", Resource_Metrics.freeram );
printf("\n Amount of shared memory %ld", Resource_Metrics.sharedram );
printf("\n Memory used by buffers %ld", Resource_Metrics.bufferram );
printf("\n Total swap space size %ld", Resource_Metrics.totalswap );
printf("\n swap space still available %ld", Resource_Metrics.freeswap );
printf("\n Number of current processes %ld", Resource_Metrics.procs );
printf("\n Total high memory size %ld", Resource_Metrics.totalhigh );
printf("\n Available high memory size %ld", Resource_Metrics.freehigh );
printf("\n Memory unit size in bytes %ld", Resource_Metrics.mem_unit );
printf("\n %ld", Resource_Metrics. );
printf("\n %ld", Resource_Metrics. );
printf("\n %ld", Resource_Metrics. );
printf("\n %ld", Resource_Metrics. );
printf("\n %ld", Resource_Metrics. );
printf("\n %ld", Resource_Metrics. );

Well, since this is a Linux Programming & Scripting forum, I have to ask why you think this will work the same way on Solaris? Wouldn't it be more appropriate to post this question to the user forums on the Sun/Oracle Solaris web site?
