[FFmpeg-devel] [PATCH] do not memset for a size of 0

[Benoit Fouet]

Hi,

the following patch fixes the linker warning:
/home/hack/ffmpeg/ffmpeg_x86/libavcodec/libavcodec.a(pcx.o): In function
`memset':


/usr/include/bits/string3.h:82: warning: memset used with constant zero
length parameter; this could be due to transposed parameters
