Recently I was working on a program that would at various junctures
run other programs using the 'system' command in Turbo C. The thing is,
no matter what command I pass system, it always returns a '0', even if
the command I'm telling it to run isn't anywhere to be found. Is this
a bug, undocumented feature, or some other unknown demon of the bytes?
Sample code:
#include <stdio.h>
#include <process.h>
main()
{
printf("----\n");
printf("call result = %d\n", system("1STICKS"));
}
-----
the program "STICKS" exists, and when I issue the call with that name,
it works fine. When I run the code above, it comes back with 'bad command or
file name' on the display (which is to be expected), but it also returns
a 0 as the call result. Does the 0 return value mean that it was able to
start up command.com only, or should I look somewhere else to get
my return values from the execution (or lack thereof) of the program?
Thanks in advance for any and all assistance.
