I'm writing a little c program and one of things I'm trying to get it to do
is cd to a particular directory and then run an exe that is on my path, as
follows...
strcpy(working_ string, "c:\\davedata\\ bats\\ks.exe fnord");
system("cd \\playtime\\d\\ build\\html");
system(working_ string);
But ks.exe does not seem to be invoked on the files in the
\\playtime\\d\\ build\\html directory.
Can someone tell me how to do this? 3 1390

The first invocation of system() creates a shell in which you do the 'cd'.
Then the shell exits. As the next step you invoke a completely new shell
by calling system() again that has no idea about the working directory of
the other shell that's already dead. Execute both commands in the _same_
call of system().

And if your shell doesn't allow this directly, build a script
containing the two commands and execute that script with system().

Not here. The C language has neither directories nor exes nor
paths. You want a group dealing with your peculiar system, which
I suspect to be either Windows or MsDos.

Hi,
I need to read the output from a system( ) function within a C program.
The function however only returns the exit status.
How can I read what system( ) sends to stdout ?
(is there a simpler way than having to fork a child process and then
catching its output ?)
(if needed: working on linux)
Thanks

I am looking for functions that can be used to automatically update the
system date and time on an NT based system, resulting from manually entered
date and time values input by an operator via a 32-bit console app. Any
ideas?..I may have to look further afield at Win32 API's, etc but I wondered
if there was any way to do it via C initially.
Merry Xmas to all !!!

I have a question that deals with the standard c library VS (Unix)

The cause of my confusion is that for example stdio.h is considered

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
