Re: [Freedos-user] Need help ... calling COMMAND.COM from C
Absolutely, the function is simple... just to see if two directories that
should have the same contents changed. Here it goes (hope it indents well):
int checkdir(void) {
int i, filesize = 0;
FILE *fp, *fp2;
system(dir c:\\data\\base1 c:\\data.dir);
fp = fopen(c:\\data.dir,r);
fp2 = fopen(c:\\dataorig.dir,r);
fseek(fp, 0, SEEK_END);
filesize = ftell(fp);
fseek(fp2, 0, SEEK_END);
if(filesize != ftell(fp2))
filesize = -1;
rewind(fp); rewind(fp2);
for(i=0;ifilesize;i++)
{
int file1data = 0, file2data = 0;
fread(file1data,1,1,fp);
fread(file2data,1,1,fp2);
if(file1data != file2data)
break;
}
if(i != filesize)
return 1;
else
return 0;
fclose(fp);
fclose(fp2);
remove(c:\\data.dir);
remove(c:\\dataorig.dir);
}
}
This always returns 1 because the file data.dir gets cut so the compare with
dataorig.dir always fails.
Thanks!!

Hi. It almost sounds to me like the destination file isn't getting flushed to the disk. I would recommend doing the recirection internally in the C program, and then you have direct control of the file. A simple close(1); open(blah, O_WRONLY); /* system() stuff here: */ blah blah blah close(1); open(CON, O_WRONLY); should do but there are also ways to 'save' the original stdout and restore it later.

This is bug in FreeCOM. And this is reason, why in my patches for

About manual redirecting: using open(CON) is wrong, because this
prevents using program with redirection. The more so, if program uses
stdio..h, this way is even more wrong. I think, better way is something
like:
int redirfd = open (d:\dirout.put, O_CREAT | O_TRUNC | O_RDWR,
S_IREAD | S_IWRITE);
if (redirfd != -1) { /* check for error */
