Detailed Description

Application interface for the SIS decoder and the SIS generator.

Author

Jean-Paul Saman jpsam.nosp@m.an@v.nosp@m.ideol.nosp@m.an.o.nosp@m.rg Application interface for the SIS decoder and the SIS generator. New decoded SIS tables are sent by callback to the application.

Macro Definition Documentation

#define dvbpsi_DeleteSIS

(

p_sis

)

Value:

do {                                                                    \
