|
Copys the value of a specified field into the given tag. The content argument may be freed after using this function. The way a content is represented in a tag depends from the tags version and kind of field. I.e. it may be nessecary to represent a track number as a binary value in a v1 tag or to embeded it into a frame for a v2 tag. The caller just needs to give the correct identifier with the value as a id3_content and to take care of freeing the id3_content value afterwards.
