try this for unambiguous option letters and getopt_long:

Code:

static struct option long_options[] = {
                  {"add", 1, 0, 0},
                  {"append", 0, 0, 0},
                  {"d", 1, 0, 0},
                  {"v", 0, 0, 0},
                  {"create", 1, 0, 'c'},
                  {"file", 1, 0, 0},
                  {0, 0, 0, 0}
              };

getopt_long_only() will handle finding "-a" versus "-append" (ambiguous options ) in the example below
NOTE: ONLY when the command line has -a for an option.

Code:

static struct option long_options[] = {
                  {"a", 1, 0, 0},
                  {"append", 0, 0, 0},
                  {"delete", 1, 0, 0},
                  {"verbose", 0, 0, 0},
                  {"create", 1, 0, 'c'},
                  {"file", 1, 0, 0},
                  {0, 0, 0, 0}
              };

curlopt_headeropt

CURLOPT_HEADEROPT(3)					     curl_easy_setopt options					      CURLOPT_HEADEROPT(3)

NAME

       CURLOPT_HEADEROPT - set how to send HTTP headers

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HEADEROPT, long bitmask);

DESCRIPTION

       Pass a long that is a bitmask of options of how to deal with headers. The two mutually exclusive options are:

       CURLHEADER_UNIFIED  - the headers specified in CURLOPT_HTTPHEADER(3) will be used in requests both to servers and proxies. With this option
       enabled, CURLOPT_PROXYHEADER(3) will not have any effect.

       CURLHEADER_SEPARATE - makes CURLOPT_HTTPHEADER(3) headers only get sent to a server and not to a proxy. Proxy headers must be set with CUR-
       LOPT_PROXYHEADER(3)  to	get  used.  Note that if a non-CONNECT request is sent to a proxy, libcurl will send both server headers and proxy
       headers. When doing CONNECT, libcurl will send CURLOPT_PROXYHEADER(3) headers only to the proxy and then CURLOPT_HTTPHEADER(3) headers only
       to the server.

DEFAULT

       CURLHEADER_SEPARATE (changed in 7.42.1, ased CURLHEADER_UNIFIED before then)

PROTOCOLS

       HTTP

EXAMPLE

       TODO

AVAILABILITY

       Added in 7.37.0

RETURN VALUE

       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
