Subject: argpar.c: add error enumerators to `enum parse_orig_arg_opt_ret`
X-Git-Url: http://git.efficios.com/?p=argpar.git;a=commitdiff_plain;h=871eba329ad77b01051cd29ec372f8ae5a401882;hp=871eba329ad77b01051cd29ec372f8ae5a401882

argpar.c: add error enumerators to `enum parse_orig_arg_opt_ret`

This patch changes `enum parse_orig_arg_opt_ret` to add

* `PARSE_ORIG_ARG_OPT_RET_ERROR_MISSING_OPT_ARG`
* `PARSE_ORIG_ARG_OPT_RET_ERROR_INVALID_OPT`
* `PARSE_ORIG_ARG_OPT_RET_ERROR_UNEXPECTED_OPT_ARG`
* `PARSE_ORIG_ARG_OPT_RET_ERROR_MEMORY`

and remove the general `PARSE_ORIG_ARG_OPT_RET_ERROR`.

No functional changes intended.

This will make it easier to switch to rich error reporting instead of
a formatted error string.
