## split_commandline()

int split_commandline | ( | OptionParseContext * | octx,
|  | int | argc,
|  | char * | argv[],
|  | const OptionDef * | options,
|  | const OptionGroupDef * | groups,
|  | int | nb_groups
| ) |  |

Split the commandline into an intermediate form convenient for further processing.

The commandline is assumed to be composed of options which either belong to a group (those with OPT_SPEC, OPT_OFFSET or OPT_PERFILE) or are global (everything else).

A group (defined by an OptionGroupDef struct) is a sequence of options terminated by either a group separator option (e.g. -i) or a parameter that is not an option (doesn't start with -). A group without a separator option must always be first in the supplied groups list.

All options within the same group are stored in one OptionGroup struct in an OptionGroupList, all groups with the same group definition are stored in one OptionGroupList in OptionParseContext.groups. The order of group lists is the same as the order of group definitions.
