* Name: getopt_long
|
|
*
|
|
* Description:
|
|
* The getopt_long() function works like getopt() except that it also
|
|
* accepts long options, started with two dashes. (If the program accepts
|
|
* only long options, then optstring should be specified as an empty
|
|
* string (""), not NULL.) Long option names may be abbreviated if the
|
|
* abbreviation is unique or is an exact match for some defined option
|
|
*
