Thread: Trouble with strtok()

I'm using this command-line parameters in my executable:

myprogram.exe c:\programmi\driver.exe c:\programmi\seti.exe

My code looks for the parameter, it is cut in 2 pieces divided by the "space" and I want to save the 2 pieces.. then every piece is cut in smaller pieces divided by "\" untill I get the executable name.. so at the end I want to print the 2 path i gave as parameter and the name of the 2 exe found in the path given :

Code:

#include <stdio.h>
#include <string.h>
#include <windows.h>


  int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, char * lpCmdLine, int  nCmdShow)

 {

  char separatoriexe[] = "\\";
  char separatori[] = " ";
  char *seti;
  char *tempseti;
  char *tempdriver;
  char *setiexe;
  char *driver;
  char *driverexe;

  driver = strtok( lpCmdLine, separatori );
  seti = strtok( NULL, separatori );
      
  tempseti = strtok( seti, separatoriexe );
    while( tempseti != NULL )
   {
      setiexe = tempseti;
      tempseti = strtok( NULL, separatoriexe );
      
   }
   
  tempdriver = strtok( driver, separatoriexe );
    while( tempdriver != NULL )
   {
      driverexe = tempdriver;
      tempdriver = strtok( NULL, separatoriexe );
      
   }

   printf( "Driver: %s\n", driver );
   printf( "Seti: %s\n", seti );   
   printf( "Exe di Seti: %s\n", setiexe );
   printf( "Exe di Driver: %s\n", driverexe );
   
    
   system("PAUSE");	
   return 0;
 }

But it seems that the strtok modify the string after the manipulation...what should I do to conserve the strings (I need them in all the code so I HAVE to conserve them)??

I get this wrong output:

Driver: c:
Seti: c:
Exe di Seti: seti.exe
Exe di Driver: driver.exe

Instead this one that is right:

Driver: c:\programmi\driver\driver.exe
Seti: c:\programmi\driver\seti.exe
Exe di Seti: seti.exe
Exe di Driver: driver.exe

help please

thanx very much for the help..

i've added

char setipath[MAX_PATH];
char driverpath[MAX_PATH];

...
...
...

strcpy (setipath, seti);
strcpy (driverpath, driver);


and it works
