I don't know of a file "xvid_decore.c", but if you talk about the examples
in xvidcore/examples

status is used as an error variable. All routines should return 0, this
means "no error". If they return something else, like 1, an error was
detected, e.g. the end of the bitstream is reached in decoding mode. 
However, since there still might be images buffered internally in the
codec, the program doesn't terminate, but continues decoding, possibly
until the maximum number of frames is reached. I don't remember exactly.

Anyway, the programs are just for illustration of the API, you can change
them to fit your needs as you wish...
