  Subject: what is "dvbpsi_pat_callback" ?


  Hi,

  I read the source "decode_pat.c"
  there is a line that is  "h_dvbpsi = dvbpsi_AttachPAT(DumpPAT, NULL);"
  here, DumpPAT is a type "dvbpsi_pat_callback"
  I found the define in pat.h
  typedef void (* dvbpsi_pat_callback)(void* p_cb_data, dvbpsi_pat_t* p_new_pat);

  but I don't understand how "dvbpsi_pat_callback" work in the program.

  Any help welcome.
