spawnvp does not work

[hpy_awad]

I wrote that program but spawnvp dows not call the exe files hello1,hello2!!!

#include <stdio.h>
#include <conio.h>
#include <process.h>

//Tv Rental system menu version 1
int user_selection();
void display_menu();
void call_program(int option,char *argv[]);
int main(int ,char *argv[])
{
int option;
do
{
display_menu();
option=user_selection();
if (option!=7) //Exit
call_program(option,argv);
}
while (option!=7);
return 0;
}


void display_menu()
{
clrscr();
printf("1 hello1");
printf("\n2 hello2");
printf("\n3 exit");
}

int user_selection()
{
int opt;
printf("\n Enter required option(1-3) : ");
scanf("%1d",&opt);
return (opt);
}

void call_program(int opt,char *argv[])
{
void delay();
switch(opt)
{
case 1:
spawnvp(0,"hello1.exe",argv);
delay();
break;
case 2:
spawnvp(0,"hello2.exe",argv);
delay();
break;
default:
printf("\n incoreect input");
delay();
exit(0);
}
}
void delay()
{
int i;
for (i=0;i<20000;i++);
}

What is this spawnvp of which you speak? It's not in my copy of the standard.

Try a windows specific newsgroup.

Did you try debugging and see what is happenning? Is the value you expect
getting to the switch statement? Do you get any error messags? You asked
this before, and I made these comments (and others) then. It was also
suggested that you ask in a newsgroup that knows what the heck spawnvp is.
The suggestions still stand.
