public final class Statm
extends ProcFile

Provides information about memory usage, measured in pages.

The columns are:

• size (1) total program size (same as VmSize in /proc/[pid]/status)
• resident (2) resident set size (same as VmRSS in /proc/[pid]/status)
• share (3) shared pages (i.e., backed by a file)
• text (4) text (code)
• lib (5) library (unused in Linux 2.6)
• data (6) data + stack
• dt (7) dirty pages (unused in Linux 2.6)
