[vorbis-dev] const char * question for vorbis API

[Akos Maroy]

Hi,

I just have a small question for the vorbis API, regarding the use of 
const char pointers. For example, in the following function:

extern void     vorbis_comment_add_tag(vorbis_comment *vc,
                        char *tag, char *contents);

which is in vorbis/codec.h, why are the tag and contents parameters not 
represented as const char pointers? are they expected to be changed by 
this function? (I suppose not.)

The way I found the problem is when I write in the darkice source:

vorbis_comment_add_tag( &vorbisComment, "TITLE", sink->getName());

I get a compiler warning of an implicit cast fron const char * to char 
*, as sink->getName() returns a const char *, for obvious reasons. And 
really, these string are not changed by the voribs API, are they? Thus 
why aren't they const char pointers?
