dos commands and C

[Ken77]

How do I execute DOS commands in C? - I want to run netstat from my program and write the results to a log.

Thanks,

K.

How about this?

#include <stdio.h>

int
main (int argc, char *argv[])
{
    if (system(&quot;netstat > /path/to/logfile&quot;) != 0)
    {
        printf(&quot;netstat failed.\r\n&quot;);
        return 1;
    }
    return 0;
}

Isn't the #include <stdlib.h> required when using system() ?

 

[jamisar]

an alternative, do you have 'popen()' ???

FILE *fd;
FILE *out;

if(!(out = fopen(&quot;logfilename&quot;,&quot;w&quot)) exit(1);
fd = popen(&quot;command-to-exec 2>&1&quot;,&quot;r&quot;
while(fgets(buff,sizeof(buff),fd)) fprintf(out,&quot;%s&quot;,buff);
pclose(fd);
fclose(out); vox clamantis in deserto.

Yes, stdlib.h is required for the system function. Sorry about that . //Daniel
