Using strcmp() after using strtok()

[ern]

//I used strtok() like this:

fgets(userCommand, MAX_COMMAND_SIZE, stdin);
g_UserCommands[0] = strtok(command, " ");
while(g_UserCommands != NULL){
i+=1;
g_UserCommands = strtok(NULL, " ");
}

//Now I want to use strcmp() like this:

if(strcmp(g_UserCommands[0], "script")==0){
return (executeScript(arg1));
}

/* Unfortuantely, I'm not getting desired results, probably because
the strings in g_UserCommands are not null terminated. Any suggestions
on a better way to get null terminated strings in g_UserCommands or
suggestions in general? I was hoping for a function that does what
strtok() does, but also providing null termination.

Thanks!

Is that the real code? If so, you are reading into the
userCommand variable and strtoking the command variable. Can
you show a complete small compilable program that shows
your problem?

strtok does terminate the strings, that is not your problem.

Replace below by a strcpy between source and destination and then you
will see the intended results

g_UserCommands = strtok(NULL, " ");
