After I run the a.out ,the cons
totalram: 995859
freeram: 34103
sharedram: 0
bufferram: 58425
totalswap: 3503615
freeswap: 3495360
procs: 895
totalhigh: 785282
freehigh: 3838
mem_unit: 4096
Using free command ,the console print that:
public@sil-01:~/coke$ free
total used free shared buffers cached
Mem: 3983436 3856212 127224 0 233264 1459520
-/+ buffers/cache: 2163428 1820008
Swap: 14014460 33020 13981440
gdb the code,it seems that the info struct had right value and the return
info.totalram has value as the sysinfo printing.After the method return the
Try Class,the *mem.t =0 .
