I don't think there is a way to make it work with incorrect
parameters :-)

How ?
The 3 functions method , the one for int parameters :
lame_set_parameter_int(lama_global_flags *lame_struct,...)
{
va_list args;
LAME_TAG_TYPE current_tag;
va_start(args);
current_tag = va_arg(args,LAME_TAG_TYPE);
while(current_tag != LAME_TAG_END )
{
switch(current_tag) {
case LAME_SET_SAMPLING_FREQ : lame_struct.samp_freq =
va_arg(args,int); break;
case LAME_SET_NR_CHAN : lame_struct.nr_channels =
va_arg(args,int); break;
/* some other integer parameters */ ....
}
current_tag = va_arg(args,LAME_TAG_TYPE);
}
va_end(args);
}
the "unified function version :
lame_set_parameters(lama_global_flags *lame_struct,...)
{
va_list args;
LAME_TAG_TYPE current_tag;
va_start(args);
current_tag = va_arg(args,LAME_TAG_TYPE);
while(current_tag != LAME_TAG_END )
{
switch(current_tag) {
case LAME_SET_SAMPLING_FREQ : lame_struct.samp_freq =
va_arg(args,int); break;
case LAME_SET_NR_CHAN : lame_struct.nr_channels =
va_arg(args,int); break;
case LAME_FILTER_WIDTH : lame_struct.filter_width =
va_arg(args,float); break;
/* some other integer, string or float or whatever parameters */
....
}
current_tag = va_arg(args,LAME_TAG_TYPE);
}
va_end(args);
}
