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 dis‐
abled. 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.
