src/readerfactory.c uses: ``` static READER_CONTEXT * sReadersContexts[PCSCLITE_MAX_READERS_CONTEXTS]; READER_STATE readerStates[PCSCLITE_MAX_READERS_CONTEXTS]; ``` A list should be used instead of the default limitation to 16 readers. With few readers (1 or 2) the RAM consumption should be lower. - sizeof(struct ReaderContext) = 440 - sizeof(sReadersContexts) = 440*16 = 7040 - sizeof(struct pubReaderStatesList) = 184 - sizeof(readerStates) = 184 * 16 = 2944 Gain when only 1 reader is in use = (7040 - 440) + (2944 - 184) = 9360 arround 9 KB of RAM would be saved.
