argv parsing

[boebox]

I am writting a program that needs to parse argv as most programs do,
here is what I have:

while ((c = getopt(argc, argv, "q:&quot) != EOF) {
switch (c) {

case 'q':
qname = optarg;
break;
default:
usage(); /* Usage will exit */
}
}

Here is argv[]: ./a.out -q test sleep 100000

I then want to fork/exec sleep 10000, how do I get sleep 1000 into a char **? Right now I can only see sleep.

i would think you need to have something like this

(This assumes sleep is followed by the value to sleep)

char* sleepCat;

...
// you currently know that argv == sleep and argv[i+1] == 10000

sleepCat = malloc(strlen(argv) + strlen(argv[i+1] +1);
sprintf(sleepCat,"%s %s",argv,argv[i+1]);

now use sleepCat to instead of the argv's

I will never learn that an "i" inside brackets [] means itallics, where argv is mentioned above assume argv[ i ]
