feedseekclr: test program for mpg123clr, showing how to use fuzzy seeking in feeder mode

|

see COPYING and AUTHORS files in distribution or http://mpg123.org

based on feedseek.c example for libmpg123.
|

|
||||
Comment (Malcolm Boczek)
|
||||
this CLR example has been written to allow easy comparison to the original feedseek.c example
|
||||
and uses some constructs that would not normally be used in a C# environment,
|
||||
eg: byte[]/ASCII text, Marshal.Copy, static fields, lots of casts etc.
