[FFmpeg-cvslog] r22860 - in trunk/libavcodec: eval.c eval.h

[stefano]

Author: stefano
Date: Mon Apr 12 22:22:55 2010
New Revision: 22860

Log:
Fix constness for func[12] parameters in ff_parse_expr() and
ff_parse_and_eval_expr().

Change func[12] attributes from "** func" to "* const * func".

This is consistent with the semantics of the provided arrays of
functions, which are not supposed to be changed by the ff_parse_*
functions.

Also fix the GCC compilation warnings:
libavcodec/ratecontrol.c: In function ?ff_rate_control_init?:
libavcodec/ratecontrol.c:109: warning: passing argument 3 of ?ff_parse_expr? discards qualifiers from pointer target type
libavcodec/eval.h:69: note: expected ?double (**)(void *, double)? but argument is of type ?double (* const*)(void *, double)?
