Redirect output into memory?

[Beach]

Rings posted an example of how to redirect output from a DOS app into memory here: viewtopic.php?t=3704 and it works fine.. on Windows..

Is there a way to do this with Linux? I know I can pipe the output to a file and read it but I was hoping for a way similar to Rings solution. I thought I read that the newer versions of PB would be able to do this... hopefully I was not dreaming...

It simpler than on Windows actually...

Code: Select all

Command$ = "df -h" 

Pipe = popen_(Command$, "r")
If Pipe

  *Buffer = AllocateMemory(2000)
  If *Buffer

    Repeat
      result = fgets_(*Buffer, 2000, Pipe)
      If result
        
        Debug PeekS(*Buffer)
        
      EndIf
    Until result = 0
  
  EndIf

  pclose_(Pipe)
Else
  Debug "Error"
EndIf

You can replace the fgets_() with any other libc command that works on streams
if you prefer another reading method.

Thank you very much!

How to write to this pipe?

[olejr]

Shange the "r" to "w":

Code: Select all

Pipe = popen_(Command$, "w") ; "w" = Write, "r" = Read

Then do something like:

Code: Select all

*Buf = AllocateMemory(2000)
If *Buf
  PokeS(*Buf, "test string")
  res = fputs_(*Buf, Pipe)  ; fputs_ = PutString (without newlinechar)
                                      ; puts_ = PutString.. (newlinechar)
EndIf

Have no idead if it will work, but in theory it should..

Here's a link with some docs to the Linux api functions.. http://www.opengroup.org/onlinepubs/007908799/

May I use your example in a GPL/LGPL program?

why not ?
