Re: [DNG] Debianising my uploaded version of netman.

[aitor_czr]

Hi Svante and Edward,

Here is is my debian/control:|

|https://git.devuan.org/aitor_czr/netman/blob/gbp-master/debian/control

I specify the |fp-units-gfx-2.6.4|version number.

I would also separate netman-backend from netman-backend-dev.

  Aitor.

For a debian package you put that requirement in the debian/control file:

Re: [DNG] gcc error: "error: unknown type name,,, ‘GtkObject’"

[aitor_czr]

Hi Edward,

The following code reads line by line the textual output of 'backend 6':

#include 

main()
{
  FILE * fp;
  char str[1024];

  fp = popen ("/usr/lib/netman/bin/backend 6", "r");

  if (fp == NULL) return -1;

  fgets (str, 1024, fp);
  while (!feof (fp))
  {
printf ("%s", str);
fgets (str, 1024, fp);
  }
  pclose (fp);
  return 0;
}

I will have a look at your code.

Thanks,

   Aitor.

Hi Aitor,

The best way for you is to use the backend's code for reference. What
you want is already implemented there. TProcesss was used to trap the
background cli commands output although there are instances where that
output is discarded.

What you need is this from the CLI backend's code (core_functions.c):
[ code snippet from getDefaultDevices() ]

FILE * shell_reader;
char scan_buffer[1024];

[...]

shell_reader = popen(command, "r");
if(!shell_reader) {
fprintf(
stderr,
"ERROR: getDefaultDevices(): "
"popen() failed (Error: %s)\n",
strerror(errno)
);

return -1;
}

char* ptr;
while((fgets(scan_buffer, 1024, shell_reader))) {
  ptr = (char*) scan_buffer;
if (strstr((char *) scan_buffer, "lo") == ptr)
continue;
else if (strstr((char *) scan_buffer, "wl") == ptr) {
snprintf(
_wl,
1024,
"%s",
(char*) scan_buffer
);
} else if (
strstr((char *) scan_buffer, "eth") == ptr ||
strstr((char *) scan_buffer, "en") == ptr 
) {
snprintf(
_eth,
1024,
"%s",
(char*) scan_buffer
);
}
}

pclose(shell_reader);


Ask again if you in the event you may need more help.

If you know it well, and if everyone else knows it well. I had some Git

But how would the average person know this?

GIT is everywhere, now. I need to stop being that guy who looks up a
few commands and dabbles with GIT, and start being a GIT expert. If a
local community college gave a semester GIT course, that would be what
I need. Failing that, a copy of "GIT For Dummies" would suffice, except
that there's no such book (and bozos unaware of trademark law label
their little tutorials as "GIT For Dummies", making things even more
difficult).

Anyone know a good source of GIT learning that's self-discoverable and
has a reasonable learning curve from know-nothing to expert?

This doesn't work: It prints the last input line twice.

Rationale: feof(fp) won't be true until a read operation actually hit
the end of the file. This means it won't be true after fgets read the
last line. fgets will then be called again for the next iteration,
causing it to detect the EOF. This leaves the contents of str unmodified
which will thus get printed again. The simple way to avoid that would be
to handle the return value of fgets:


#include 

int main(void)
{
  FILE * fp;
  char str[1024];

  fp = popen ("cat /etc/passwd", "r");

  if (fp == NULL) return -1;

  while (fgets (str, 1024, fp))
printf ("%s", str);
  
  pclose (fp);
  return 0;
}


Omitting the return value of a function for a default of 'int' isn't
standard-conforming C anymore more and using () as synonym for "whatever
the caller desired to pass" is 'an obsolescent feature' (although
sometimes useful). The C way to denote an empty argument list is (void),
() means the same in C++.

Re: [DNG] DNG/Gmail Bounces (was: XFCE terminal alternatives?)

[Neo Futur]

 hi all, concerning gmail/google apps bounces, I recently discovered :

https://support.google.com/mail/answer/6227174?hl=en
https://postmaster.google.com/

 this is relatively new and few people needed it un til now, but it
seems important to seup for anyone sending an important volume of
emails to gmail/google apps mail accounts, parlticularly mailing
lists, and this could be the reason for the problems this mailing list
have seen recently.

Re: [DNG] gcc error: "error: unknown type name,,, ‘GtkObject’"

[Edward Bartolo]

Hi Aitor,

I think, the fgets outside the loop is not required. I think it can be
done this way:

#include 

main()
{
  FILE * fp;
  char str[1024];

  fp = popen ("/usr/lib/netman/bin/backend 6", "r");

  if (fp == NULL) return -1;

  while (!feof (fp))
  {
fgets (str, 1024, fp);
printf ("%s", str);
  }
  pclose (fp);
  return 0;
}

The reasoning behind my version:
If file fp is 0 in length feof(fp) should return true (non zero) which
means the loop does not start. if fp is not zero in length the loop
starts, fgets reads the first line and printf print it to the screen.
This continues until feof(fp) returns non zero (true).
