From: Ben Pfaff Date: Mon, 20 Sep 2010 04:36:58 +0000 (-0700) Subject: data-in: Make data_in() parameters more uniform. X-Git-Tag: v0.7.6~182 X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=38993354cabb6fc37bb882be92f9a49e9aeb4c88;p=pspp-builds.git data-in: Make data_in() parameters more uniform. data_in() essentially takes an input encoding and an output encoding but the parameters were in inconsistent order, inconsistently named, and had inconsistent types. This commit changes all that to, I hope, be easier to understand. --- diff --git a/perl-module/PSPP.xs b/perl-module/PSPP.xs index 0e918a9f..bf90d986 100644 --- a/perl-module/PSPP.xs +++ b/perl-module/PSPP.xs @@ -655,9 +655,8 @@ CODE: { struct substring ss = ss_cstr (SvPV_nolen (sv)); if ( ! data_in (ss, LEGACY_NATIVE, ifmt->type, 0, 0, - sfi->dict, - case_data_rw (c, v), - var_get_width (v)) ) + case_data_rw (c, v), var_get_width (v), + dict_get_encoding (sfi->dict))) { RETVAL = 0; goto finish; diff --git a/src/data/data-in.c b/src/data/data-in.c index b8226b37..de19d670 100644 --- a/src/data/data-in.c +++ b/src/data/data-in.c @@ -79,17 +79,16 @@ static bool trim_spaces_and_check_missing (struct data_in *); static int hexit_value (int c); /* Parses the characters in INPUT, which are encoded in the given - ENCODING, according to FORMAT.
