Tcl wrapper over net-snmp library
This is a multi-part message in MIME format.
------_=_NextPart_001_01C5EF93.4B8F388A Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Hi, We are writing a Tcl Wrapper over the NET-SNMP library as we did not = want to use the library executables directly because of performance = issues. The library uses fprintf(stderr,...) statements to print the ouput. With the Tcl Wrapper, the net-snmp commands can be executed from the tcl = shell as commands.=20 The problem is, the output of the command execution is displayed on the = terminal because of the fprintf's used within the library. Since I am = calling the command from within a tcl script, I am not able to capture = the result (printed on the stderr).=20 I execute the net-snmp commands by using=20 if {![catch {eval $cmd} status]} { #print the required message or the result=20 } There is nothing stored in the status variable. I would appreciate any kind of help here... Thanks & regards, Sanjib. ------_=_NextPart_001_01C5EF93.4B8F388A Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><HTML = DIR=3Dltr><HEAD><META HTTP-EQUIV=3D"Content-Type" CONTENT=3D"text/html; = charset=3Diso-8859-1"></HEAD><BODY><DIV><FONT face=3D'Arial' = color=3D#000000 size=3D2><FONT size=3D2>=0A= <P>Hi,</P>=0A= <P>We are writing a Tcl Wrapper over the NET-SNMP library as we did not = want to =0A= use the library executables directly because of performance issues.</P>=0A= <P>The library uses fprintf(stderr,...) statements to print the = ouput.</P>=0A= <P>With the Tcl Wrapper, the net-snmp commands can be executed from the = tcl =0A= shell as commands. </P>=0A= <P>The problem is, the output of the command execution is displayed on = the =0A= terminal because of the fprintf's used within the library.
