unsigned char* songid_pack | ( | njb_songid_t * | song, |
u_int32_t * | tagsize | ||
) |
This packs (serialize, marshal) a libnjb song ID into the raw byte structure used by the NJB1.
song | the libnjb song ID to pack |
tagsize | a pointer to an integer that will hold the size of the resulting NJB1 songid structure |
