 Stimmt ist für eine Konsolenanwendung glaub ich optimal.
Kleiner Auszug aus MSDN:
| Code: | system, _wsystem
Execute a command.
int system( const char *command );
int _wsystem( const wchar_t *command );
Routine Required Header Compatibility
system <process.h> or <stdlib.h> ANSI, Win 95, Win NT
_wsystem <process.h> or <stdlib.h> or <wchar.h> Win NT
For additional compatibility information, see Compatibility in the Introduction.
Libraries
LIBC.LIB Single thread static library, retail version
LIBCMT.LIB Multithread static library, retail version
MSVCRT.LIB Import library for MSVCRT.DLL, retail version
Return Value
If command is NULL and the command interpreter is found, the function returns a nonzero value. If the command interpreter is not found, it returns 0 and sets errno to ENOENT. If command is not NULL, system returns the value that is returned by the command interpreter. It returns the value 0 only if the command interpreter returns the value 0. A return value of – 1 indicates an error, and errno is set to one of the following values:
E2BIG
Argument list (which is system-dependent) is too big.
ENOENT
Command interpreter cannot be found.
ENOEXEC
Command-interpreter file has invalid format and is not executable.
ENOMEM
Not enough memory is available to execute command; or available memory has been corrupted; or invalid block exists, indicating that process making call was not allocated properly.
Parameter
command
Command to be executed
Remarks
The system function passes command to the command interpreter, which executes the string as an operating-system command. system refers to the COMSPEC and PATH environment variables that locate the command-interpreter file (the file named CMD.EXE in Windows NT). If command is NULL, the function simply checks to see whether the command interpreter exists.
You must explicitly flush (using fflush or _flushall) or close any stream before calling system.
_wsystem is a wide-character version of system; the command argument to _wsystem is a wide-character string. These functions behave identically otherwise.
