This struct allows you to define long options. The syntax for
declaring the array is just like that of getopt's longopts.
(see getopt(3))
This struct allows you to define long options:
static const struct option applet_long_options[] = {
//name,has_arg,flag,val
{ "verbose", 0, 0, 'v' },
{ 0, 0, 0, 0 }
};
applet_long_options = applet_long_options;
static const char applet_longopts[] =
//"name\0" has_arg val
"verbose\0" No_argument "v"
"\0";
applet_long_options = applet_longopts;
The last member of struct option (val) typically is set to
matching short option from applet_opts. If there is no matching
char in applet_opts, then:
- return bit have next position after short options
- if has_arg is not "no_argument", use ptr for arg also
- if has_arg is not "No_argument", use ptr for arg also
- opt_complementary affects it too
