@ -137,6 +137,10 @@ There are some macros to easily define options:
Introduce a boolean option.
If used, `int_var` is bitwise-ored with `mask`.
`OPT_NEGBIT(short, long, &int_var, description, mask)`::
Introduce a boolean option.
If used, `int_var` is bitwise-anded with the inverted `mask`.
`OPT_SET_INT(short, long, &int_var, description, integer)`::
Introduce a boolean option.
If used, set `int_var` to `integer`.
@ -166,6 +170,14 @@ There are some macros to easily define options:
`OPT_ARGUMENT(long, description)`::
Introduce a long-option argument that will be kept in `argv[]`.
`OPT_NUMBER_CALLBACK(&var, description, func_ptr)`::
Recognize numerical options like -123 and feed the integer as
if it was an argument to the function given by `func_ptr`.
The result will be put into `var`. There can be only one such
option definition. It cannot be negated and it takes no
arguments. Short options that happen to be digits take
precedence over it.
The last element of the array must be `OPT_END()`.
