CONFORMING TO
       This function is Linux-specific, and should not be used in
       programs intended to be portable.

DESCRIPTION
       sysinfo returns information in the following structure:

              struct sysinfo {
                   long uptime;              // Seconds since boot 
                   unsigned long loads[3];   // 1, 5, and 15 minute load average
s 
                   unsigned long totalram;   // Total usable main memory size 
                   unsigned long freeram;    // Available memory size 
                   unsigned long sharedram;  // Amount of shared memory 
                   unsigned long bufferram;  // Memory used by buffers 
                   unsigned long totalswap;  // Total swap space size 
                   unsigned long freeswap;   // swap space still available 
                   unsigned short procs;     // Number of current processes 
                   char _f[22];              // Pads structure to 64 bytes
