I am having a problem getting an external function (written in C) to correctly use the 'seek' functions like mi_lo_readwithseek() and mi_lo_seek(). The problem appears to stem from the mi_int8 *offset value. What is offset (is it bytes, bits) and what is the difference between that and seek_pos? I can do a bunch of mi_lo_read()s to get to the spot in the blob that I want, but that seems ridiculous and slow. Otherwise I get memory failure errors. Can anyone provide an example of how these functions are used? Thanks. Jack
