I want to run a program from the program im writing. For example when
my program is running I want it to open up an internet explorer window.
I have been searching and found that there is a RUN command, it won't
run with any library that I know. so what i am asking for is a way to
call other programs, or the header file nescarrary to use the RUN
command. 10 3726 sa***********@g mail.com wrote: I want to run a program from the program im writing. For example when my program is running I want it to open up an internet explorer window.

The system(const char *) function is available in cstdlib. Look at the
following code:
ken@ken-wn0vf73qmks ~/c
$ cat run.cpp
#include <cstdlib>
#include <cstdio>
int main(int argc, char **argv) {
if(argc == 2) system(argv[1]);
else printf("Usage: %s [program-name]\n", argv[0]);
return 0;
}
ken@ken-wn0vf73qmks ~/c
$ ./run ./test
1: Hello!, 2: Hello!, 3: Hello!
Hi12345, Hello!

The system(const char *) function is available in cstdlib. Look at the following code:
Its not a function, its a macro and its not c++ either. So you are off
topic.
Redirecting the OP to the appropriate newsgroup is beneficial for both the
users here and the OP. For example, in this specific case, cstdlib's system
macro isn't the recommended way to launch that application and the
executable in question is not found in the windows environment path. ken@ken-wn0vf73qmks ~/c $ cat run.cpp #include <cstdlib> #include <cstdio>
int main(int argc, char **argv) { if(argc == 2) system(argv[1]); else printf("Usage: %s [program-name]\n", argv[0]); return 0; }
ken@ken-wn0vf73qmks ~/c $ ./run ./test 1: Hello!, 2: Hello!, 3: Hello! Hi12345, Hello!

The system(const char *) function is available in cstdlib. Look at the following code:
Its not a function, its a macro
Cygwin declares system as:
#define _EXFUN(name, proto) __cdecl name proto
int _EXFUN(system,( const char *__string));
The latest MSVS.NET declares it as:
_CRTIMP int __cdecl system(const char *);
Those are some odd looking macros. If you're interested in the
definitions for these functions, I can accommodate.
and its not c++ either. So you are off topic.
Last I checked, cstdlib was a standard C++ header. Redirecting the OP to the appropriate newsgroup is beneficial for both the users here and the OP. For example, in this specific case, cstdlib's system macro isn't the recommended way to launch that application and the executable in question is not found in the windows environment path.
Redirecting the OP didn't answer his question. He was asking about a
RUN() function and was most likely talking about system().

If it is not standard c++ language, then redirecting to proper newsgroup
is much better response. He is likely to get more correct answer from
that 'dedicated' group.

From C90 which applies in C++98 too:
4.10.4.5 The system function
Synopsis
#include <stdlib.h>
int system(const char *string);
Description
The system function passes the string pointed to by string to the host environment to be
executed by a command processor in an implementation-defined manner. A null pointer may be
used for string to inquire whether a command processor exists.
Returns
If the argument is a null pointer, the system function returns nonzero only if a command
processor is available. If the argument is not a null pointer, the system function returns
an implementation-defined value."
In other words it is not a macro.
For example, in this specific case, cstdlib's system macro
function
isn't the recommended way to launch that application
Why?
and the executable in question is not found in the windows environment path.
Are you talking about Internet Explorer?

Check your standard. App 3.2.7. It clearly claims system() as a
standard C++ function. Context around this subclause clearly states
that system() is indeed a function, not a macro.

Depends on your definition of "c++". Here, people usually define it as "the
language defined by ISO/IEC 14882", and in that language, the headers
<stdlib.h> and <cstdlib> do declare such a function.
So you are off topic.
Nope.

It is the best way the standard offers.
and the executable in question is not found in the windows environment path.
Well, other functions that might guarantee something like that are off-topic
here ;-) This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |
