C++ (Cpp) apply_profile Examples

Example #1

File: profile.cpp Project: dyne/MuSE

bool Profile::default_profile() {
  /* loads the default */
  if(!load_profile("default")) {
    if(!create_default_profile()) {
      error("can't create default profile %s", profile_path); 
      return false;
    }
  }
  return apply_profile();
}

Example #2

File: out_lame.cpp Project: rektide/dyne-muse

bool OutLame::init() {
  func("initializing %s %s",name,version);

  if(!apply_profile()) {
    error("problems in setting up codec parameters");
    lame_close(enc_flags);
    enc_flags = NULL;
    return false;
  }

  initialized = true;
  return initialized;
}
