* Parse command line parameters.
|
|
|
|
*
|
|
|
|
* Walks the command line parameters and parse them based on @a parser
|
|
|
|
* description, doing actions based on @c parser->descs->action, like
|
|
|
|
* showing help text, license, copyright, storing values in values and
|
|
|
|
* so on.
|
|
|
|
*
|
|
|
|
* It is expected that values is of the same size than @c parser->descs,
|
|
|
|
* options that do not need a value it will be left untouched.
|
|
|
|
*
|
|
|
|
* All values are expected to be initialized before use. Options with
|
|
|
|
* action @c ECORE_GETOPT_ACTION_STORE and non required arguments
|
|
|
|
* (others than @c ECORE_GETOPT_DESC_ARG_REQUIREMENT_YES), are expected
|
|
|
|
* to provide a value in @c def to be used.
|
|
|
|
*
|
|
|
|
* The following actions will store 1 on value as a boolean
|
|
|
|
* (@c value->boolp) if it's not NULL to indicate these actions were executed:
|
|
|
|
* - @c ECORE_GETOPT_ACTION_HELP
|
|
|
|
* - @c ECORE_GETOPT_ACTION_VERSION
|
|
|
|
* - @c ECORE_GETOPT_ACTION_COPYRIGHT
|
|
|
|
* - @c ECORE_GETOPT_ACTION_LICENSE
|
|
|
|
*
|
|
|
|
* Just @c ECORE_GETOPT_ACTION_APPEND will allocate memory and thus
|
|
|
|
* need to be freed. For consistency between all of appended subtypes,
|
|
|
|
* @c eina_list->data will contain an allocated memory with the value,
|
|
|
|
* that is, for @c ECORE_GETOPT_TYPE_STR it will contain a copy of the
|
|
|
|
* argument, @c ECORE_GETOPT_TYPE_INT a pointer to an allocated
|
|
|
|
* integer and so on.
|
|
|
|
*
|
|
|
|
* If parser is in strict mode (see @c Ecore_Getopt->strict), then any
|
|
|
|
* error will abort parsing and -1 is returned. Otherwise it will try
|
|
|
|
* to continue as far as possible.
|
|
|
|
*
|
|
|
|
* This function may reorder @a argv elements.
|
|
|
|
*
|
|
|
|
* @param parser description of how to work.
|
|
|
|
* @param value where to store values, it is assumed that this is a vector
|
|
|
|
* of the same size as @c parser->descs. Values should be previously
|
|
|
|
* initialized.
|
|
|
|
* @param argc how many elements in @a argv. If not provided it will be
|
|
|
|
* retrieved with ecore_app_args_get().
|
|
|
|
* @param argv command line parameters.
|
|
|
|
*
|
|
|
|
* @return index of first non-option parameter or -1 on error.
