[vlc-commits] core: add vlc_MetadataRequest

[Filip Roséen]

vlc/vlc-3.0 | branch: master | Filip Roséen <filip at atch.se> | Wed Jul 25 04:06:38 2018 +0200| [f7f301cce34a93324efa572f181552fb0cb361a8] | committer: Jean-Baptiste Kempf

core: add vlc_MetadataRequest

This function is to be used by entities within the core that would
like to spawn a metadata request. Such request will not have the
implicit recursiveness of libvlc_MetadataRequest (which is to be
called by users of libvlc).
