[DVDnav-discuss] is "this" a valid c++ variable name?

[Andrea]

Hi,

either I am 100% stupid or "this" is not valid in c++ as a variable name.

this is line 293 of dvdnav.h

uint32_t dvdnav_describe_title_chapters(dvdnav_t *this, int32_t title, uint64_t **times, uint64_t 
*duration);

it is the only "this" in this file, all other arguments are called "self".
g++ 4.3.0 does not compile it

/usr/include/dvdnav/dvdnav.h:293: error: expected ‘,’ or ‘...’ before ‘this’

am I wrong?

Andrea
