I need the console to open when there's some output being written, and the user must be able close it (not dispose, just close/hide it). Next time some output is written the window opens again.

#include <stdio.h>

int main()
{
FILE *f;
char *file = "CON:100/100/320/256/Filer output/CLOSE/AUTO";

if((stdout = freopen(file,"w",stdout)))
{
while(1)
{
char buffer[256];
gets(buffer);
printf("%s\n",buffer);
if(!strcmp(buffer,"QUIT"))
{
break;
}
}
fclose(f);
}else
{
printf("Faild to open %s\n",file);
}
}

#include <stdio.h>

#include <proto/dos.h>

int main()
{
char *file = "CON:100/100/320/256/Filer output/CLOSE/AUTO";
BPTR new;
if((new = IDOS->Open(file,MODE_NEWFILE)))
{
BPTR old = IDOS->SelectOutput(new);

while(1)
{
char buffer[256];
gets(buffer);
IDOS->Printf("%s\n",buffer);
if(!strcmp(buffer,"QUIT"))
{
break;
}
}

IDOS->SelectOutput(old);
IDOS->Close(new);
}
}

The stderr/stdout streams are not changed by SelectOutput/SelectErrorOutput.

The OS function for checking file type just reports the actual type without any relation to any parent 'group'. It might not even be possible to read the system deficon type tree, but that's just a guess.

WaitIO always crashes though. Removing it and it works.
