Created page with "#include <stdio.h> #include <unistd.h> #include <errno.h> void invarg(int Qparametri, char* Rargv[], char* argv[]); int main(int argc, char* argv[]){ int Qparametri=argc-1;..."

New page

#include <errno.h>

void invarg(int Qparametri, char* Rargv[], char* argv[]);

int main(int argc, char* argv[]){
int Qparametri=argc-1;
char *Rargv[Qparametri];
invarg(Qparametri, Rargv, argv);
printf("%s\n","il nuovo vettore dei parametri è stato creato con successo");
execvp(Rargv[0], Rargv);
perror("execvp");
return 1;

}

void invarg(int Qparametri, char* Rargv[], char* argv[]){

int i=2;
while(argv[i]!=NULL){
