Linked to my previous Topic “PtRaw use”:
In order to use PgGetVideoMode, PgGetVideoModeInfo, PgGetPalette, PgGetGraphicsHWCaps, Tutorial QNX always say “You must target this function at a specific card by calling PdSetTargetDevice …”
So, I suppose that PdSetTargetDevice has to be called before one of these functions.
My problem is that my calls to above functions return always errors : when I try to use PdSetTargetDevice or not.
I looked for examples on web and I find a lot of use case where these functions are used without previous call to PdSetTargetDevice.
So, is PdSetTargetDevice mandatory ? If yes, how to use it ? If not, what does the tutorial mean ?
