17 This routine will allocate enough memory to save the current option
18 processing state. If this routine has been called before, that memory
19 will be reused. You may only save one copy of the option state. This
20 routine may be called before optionProcess(3AO). If you do call it be‐
21 fore the first call to optionProcess, then you may also change the con‐
22 tents of argc/argv after you call optionRestore(3AO)
23
24 In fact, more strongly put: it is safest to only use this function be‐
25 fore having processed any options. In particular, the saving and
26 restoring of stacked string arguments and hierarchical values is dis‐
27 abled. The values are not saved.

33 If it fails to allocate the memory, it will print a message to stderr
34 and exit. Otherwise, it will always succeed.
