proci - Go Lang Process Information Library

proci is a Go library that provides a set of functions for listing processes and get following information for each process:

• The process path and name
• The process command line (that was executed when the process was started)
• The process RAM memory usage

Additionaly this library has functions for get:

• The total physical RAM memory installed on the computer
• The available physical RAM memory on the computer

Supported platforms:

• Windows 64 bit

More platforms might be added in future.

To see the full list of proci functions, check out the documentation on godoc.org

Example Usage

package main

import (
	"fmt"
	"github.com/midstar/proci"
)

func main() {
  pids := proci.GetProcessPids()
  for i:=0 ; i < len(pids) ; i++ {
    pid := pids[i]
    if pid == 0 {
      // This is the idle process. No operations can be performed on it.
      continue
    }
    path, patherr := proci.GetProcessPath(pid)
    if patherr != nil {
      fmt.Println("  GetProcessPath for PID", pid, "returned error:", patherr)
    }
    fmt.Println("  Path:", path)
    commandLine, cmderr := proci.GetProcessCommandLine(pid)
    if cmderr != nil {
      // Expected for some Windows system processes.
      fmt.Println("  Unable to read command line for PID", pid," error: ", cmderr)
    } else {
      fmt.Println("  Command line:", commandLine)
    }
    memoryUsage, memerr := proci.GetProcessMemoryUsage(pid)
    if memerr != nil {
      fmt.Println("  GetProcessMemoryUsage for PID", pid, "returned error:", memerr)
    }
    fmt.Println("  Memory usage:", memoryUsage, "B (", memoryUsage / 1024 / 1024, "MB )")
  }
}
