system date and time update

P: n/a
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 !!!

No, not with ISO C. You'll want a win32 newsgroup where they can tell you
how to do it in Windows NT. ISO C does not deal with system specific
details like this (or serial ports, or graphic cards, or parallel ports,
etc.)

(The below welcome text was originally written by Ben Pfaff)

Your question is outside the domain of comp.lang.c, which discusses
only the standard C programming language, including the standard C
library. This is a remarkably narrow topic compared to what many
people expect.

For your convenience, the list below contains topics that are not
on-topic for comp.lang.c, and suggests newsgroups for you to explore
if you have questions about these topics. Please do observe proper
netiquette before posting to any of these newsgroups. In particular,
you should read the group's charter and FAQ, if any (FAQs are
available from www.faqs.org and other sources). If those fail to
answer your question then you should browse through at least two weeks
of recent articles to make sure that your question has not already
been answered.

* OS-specific questions, such as how to clear the screen,
access the network, list the files in a directory, or read
"piped" output from a subprocess. These questions should be
directed to OS-specific newsgroups, such as
comp.os.ms-windows.programmer.misc, comp.unix.programmer, or
comp.os.linux.development.apps.

* Compiler-specific questions, such as installation issues and
locations of header files. Ask about these in
compiler-specific newsgroups, such as gnu.gcc.help or
comp.os.ms-windows.programmer.misc. Questions about writing
compilers are appropriate in comp.compilers.

* Processor-specific questions, such as questions about
assembly and machine code. x86 questions are appropriate in
comp.lang.asm.x86, embedded system processor questions may
be appropriate in comp.arch.embedded.

* ABI-specific questions, such as how to interface assembly
code to C. These questions are both processor- and
OS-specific and should typically be asked in OS-specific
newsgroups.

* Algorithms, except questions about C implementations of
algorithms. "How do I implement algorithm X in C?" is not a
question about a C implementation of an algorithm, it is a
request for source code. Newsgroups comp.programming and
comp.theory may be appropriate.

* Making C interoperate with other languages. C has no
facilities for such interoperation. These questions should
be directed to system- or compiler-specific newsgroups. C++
has features for interoperating with C, so consider
comp.lang.c++ for such questions.

* The C standard, as opposed to standard C. Questions about
the C standard are best asked in comp.std.c.

* C++. Please do not post or cross-post questions about C++
to comp.lang.c. Ask C++ questions in C++ newsgroups, such
as comp.lang.c++ or comp.lang.c++.moderated.

* Test posts. Please test in a newsgroup meant for testing,
such as alt.test.

news.groups.questions is a good place to ask about the appropriate
newsgroup for a given topic.

If NT accepts a command-line to do this the way Unix accepts a date command,
it might be easiest to sprintf the command to a string and then call
system() to run the command.

On unix I would do something like
char command[1000];
sprintf(command,"date %04d%02d%02d%02d%02d.%02d",
year,month,day,hour,minute,second);
if (system(command)!=0) {error-processing;}

This XP machine here, and any MSWindows machine I have used, has DATE to
check/set the date and TIME to check/set the time.Why do you want to write a
C program to do the same job?
