From: Limin Wang <[email protected]> Nicolas George comments for the macros: These functions have a terrible design, let us fix them before extending them. First design mistake: no error code. A helper function for testing memory allocation failure where AVERROR(ENOMEM) does not appear is absurd.
Second design mistake: printing a message. Return the error code, let the caller print the error message. Third design mistake: hard-coded use of goto. http://ffmpeg.org/pipermail/ffmpeg-devel/2020-May/262544.html Signed-off-by: Limin Wang <[email protected]> --- libavutil/internal.h | 36 ------------------------------------ 1 file changed, 36 deletions(-) diff --git a/libavutil/internal.h b/libavutil/internal.h index 00f1a57..b87cc6d 100644 --- a/libavutil/internal.h +++ b/libavutil/internal.h @@ -140,42 +140,6 @@ #define FF_ALLOC_TYPED_ARRAY(p, nelem) (p = av_malloc_array(nelem, sizeof(*p))) #define FF_ALLOCZ_TYPED_ARRAY(p, nelem) (p = av_mallocz_array(nelem, sizeof(*p))) -#define FF_ALLOC_OR_GOTO(ctx, p, size, label)\ -{\ - p = av_malloc(size);\ - if (!(p) && (size) != 0) {\ - av_log(ctx, AV_LOG_ERROR, "Cannot allocate memory.\n");\ - goto label;\ - }\ -} - -#define FF_ALLOCZ_OR_GOTO(ctx, p, size, label)\ -{\ - p = av_mallocz(size);\ - if (!(p) && (size) != 0) {\ - av_log(ctx, AV_LOG_ERROR, "Cannot allocate memory.\n");\ - goto label;\ - }\ -} - -#define FF_ALLOC_ARRAY_OR_GOTO(ctx, p, nelem, elsize, label)\ -{\ - p = av_malloc_array(nelem, elsize);\ - if (!p) {\ - av_log(ctx, AV_LOG_ERROR, "Cannot allocate memory.\n");\ - goto label;\ - }\ -} - -#define FF_ALLOCZ_ARRAY_OR_GOTO(ctx, p, nelem, elsize, label)\ -{\ - p = av_mallocz_array(nelem, elsize);\ - if (!p) {\ - av_log(ctx, AV_LOG_ERROR, "Cannot allocate memory.\n");\ - goto label;\ - }\ -} - #include "libm.h" /** -- 1.8.3.1 _______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
