* avutil/attributes: add av_warn_unused_resultGanesh Ajjanagadde2015-10-05
| | | | | | | | | | | | | | GCC 3.4 introduced an attribute warn_unused_result to warn when a programmer discards the return value. Applying this judiciously across the codebase can help in fixing a lot of problems. At a high level, functions which return error codes should always be checked. More concretely, consider the functions ff_add_format and the like in avfilter/formats.h. A quick examination shows that a large portion of libavfilter fails to handle the associated errors, usually AVERROR(ENOMEM). The above example was where I observed the utility of this, but it should be useful in many places across the code base.

| | | | | | | | | | | | | | | | | | | | | | Prior to this on msvc/icl there was no handling of deprecated functions and the deprecated warning was disabled. After enabling there are a number of warnings relating to the CRT and the use of the non-secure versions of several functions. Defining _CRT_SECURE_NO_WARNINGS silences these warnings.
