How to handle stdout and stderr on PSP?

[carvalhotk]

Hello, there.

The question is that: how is the right way to handle stdout and stderr on the PSP? I mean, I can't just use pspDebugScreenPrintf, because the libraries that are extern to my program don't use it. So, I fell like I have to redirect the output to files, but as I have seen, it's not a good way to do it.

For example, if I use the following code:

Code: Select all

FILE *fp_out = NULL;
FILE *fp_err = NULL;

void PSP_quit()
{
  if (fp_out) {
    fclose(fp_out);
  }
  if (fp_err) {
    fclose(fp_err);
  }
  sceKernelExitGame();
}

int main(int argc, char **argv)
{
  [ setup the exit callback... ]

  fp_out = freopen("stdout", "w", stdout);
  fp_err = freopen("stderr", "w", stderr);

  atexit(PSP_quit);

  [ run my program, use puts on my Ruby scripts, and so ...]

  exit(EXIT_SUCCESS);
}

It'll not work. Ive tried to run the following ruby script:

Code: Select all

i = 0
while i < 100
  puts "Iteration #&#123;i.to_s&#125;"
  i += 1
end

The program runs fine, finalizes fine, but my stdout looks like:

Code: Select all

Iteration 0
Iteration 1
[...]
Iteration 76
Iterat
EOF

Thank you guys.

Are you sure the atexit handler is being called?

stderr works correctly if you test your application through PSPLink, no Voodoo magic is required, so I'm not entirely sure what you're trying to accomplish...

You can just include stdio.h and do not redefine printf then you can use standard C library and get output from PSPLink,

Thank you, guys. This psplink thing is amazing!
