optionSaveState(3)            Programmer's Manual           optionSaveState(3)

NAME
       optionSaveState - saves the option state to memory


SYNOPSIS
       #include <your-opts.h>
       cc [...] -o outfile infile.c -lopts [...]

       void optionSaveState(tOptions * pOpts);


DESCRIPTION
       This routine will allocate enough memory to save the current option
       processing state.  If this routine has been called before, that memory
       will be reused.  You may only save one copy of the option state.  This
       routine may be called before optionProcess(3AO).  If you do call it
       before the first call to optionProcess, then you may also change the
       contents of argc/argv after you call optionRestore(3AO)

       In fact, more strongly put: it is safest to only use this function
       before having processed any options.  In particular, the saving and
       restoring of stacked string arguments and hierarchical values is
       disabled.  The values are not saved.

       pOpts  program options descriptor


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