getopt_long() problems

[Karthik]

hi everyone,

I am using getopt_long() in one of my programs to parse out the
command line arguments.

The library call returns a character code of "1" which i am not sure
whether it is a errno or what it is.

The code snippet is :

---code---

static struct option const long_opts[] =
{
{"directory", no_argument, NULL, 'd'},
{"force", no_argument, NULL, 'f'},
{"interactive", no_argument, NULL, 'i'},
{"recursive", no_argument, NULL, 'r'},
{"verbose", no_argument, NULL, 'v'},
{NULL, 0, NULL, 0}
};
.......
.......

int c = 0;

while ((c = getopt_long (argc, argv, "dfirvR", long_opts, NULL)) !=
EOF)
{
fprintf(stderr,"Value of c is : %d \n",c);

switch(c) {
.....

default:
fprintf(stderr,"I am here 1\n");
usage (1);

}
}

---code---
Output from the program: [partial ..coz rest is not needed in this
case]

---output---

Value of c is : 1
I am here 1

[usage text ]

---output---

Actually the usage text is being displayed multiple times ..say like
10 times or something. I am really confused and dont know what to do.
Any help is highly appreciated.

TIA

getopt is not a part of standard C. Maybe comp.unix.programmer?
And you should not expect direct e-mails, especially when you hide
your address. If the reply-to: field was set correctly you MIGHT
get the occasional direct reply, but in general the rule is "ask
here, read here".

Thanx for the suggestion. This is my first post to a USENET group and i
was not sure how to go about doing everything. Now i kinda figured it
out. Will not request a direct reply next time.
