X-Git-Tag: v0.7.7~113 X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2a02ce128ba2c77fd003e81195730de4f82d3baa;p=pspp-builds.git categoricals: Make parameter to categoricals_done() const. From a high-level point of view, categoricals_done() does not actually mutate any data in a categoricals object. Instead, it just computes a cache. So it seems reasonable to make it take a "const" parameter, and this fixes a warning: oneway.c: In function ‘run_oneway’: oneway.c:502: warning: initialization discards qualifiers from pointer target type --- diff --git a/src/language/stats/oneway.c b/src/language/stats/oneway.c index 12170bb4..0a2b8e71 100644 --- a/src/language/stats/oneway.c +++ b/src/language/stats/oneway.c @@ -501,7 +501,7 @@ run_oneway (const struct oneway_spec *cmd, for (v = 0; v < cmd->n_vars; ++v) { - struct categoricals *cats = covariance_get_categoricals (ws.vws[v].cov); + const struct categoricals *cats = covariance_get_categoricals (ws.vws[v].cov); categoricals_done (cats); diff --git a/src/math/categoricals.c b/src/math/categoricals.c index c8b337e4..25de2cc6 100644 --- a/src/math/categoricals.c +++ b/src/math/categoricals.c @@ -1,5 +1,5 @@ /* PSPP - a program for statistical analysis. - Copyright (C) 2009 Free Software Foundation, Inc. + Copyright (C) 2009, 2010 Free Software Foundation, Inc.
