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.
