[cups-devel] how to get supported media information for a particular printer

[My Sadhukhan]

Hi All,

I was trying to find the supported media for a particular printer using
non-ppd based API but am encountering a problem.

























*void getMedia(char *name){    cups_dest_t dest;    dest.name
<http://dest.name> = name;    dest.instance = name;    dest.is_default =
0;    cups_dinfo_t *info = cupsCopyDestInfo(CUPS_HTTP_DEFAULT, &dest);;
if (info == NULL) {        printf("CopyDestInfo Request failed %s\n",
cupsLastErrorString());    }    ipp_attribute_t *media =
cupsFindDestSupported(CUPS_HTTP_DEFAULT,
&dest, info, CUPS_MEDIA);    if (media != NULL) {        int i, count =
ippGetCount(media);        printf("count %d\n", count);        for (i = 0;
i < count; i++)            printf(" %s\n", ippGetString(media, i,
NULL));    } else {        printf("FindDestSupported Request failed %s\n",
cupsLastErrorString());    }}int main(void){
getMedia("Ricoh-Aficio-MP-5002");*
*}*

I am getting
-----------
CopyDestInfo Request failed (null)
FindDestSupported Request failed Invalid argument
-----------

Earlier, I was using
char filename = cupsGetPPD("Ricoh-Aficio-MP-5002");
ppd_file_t *ppd = ppdOpenFile(filename);
ppd_option_t *optionPage = ppdFindOption(ppd, "PageSize") and get
optionPage->choices->text
to get the below supported media size information obtained from that
printer ppd.
That is, in* /etc/cups/ppd/Ricoh-Aficio-MP-5002.ppd*,
I have this and I am interested in getting "A3", "A4", "A5", "A6", "B4",
"B5"..."EngQuatro.FullBleed" etc.

but now, since ppd API is deprecated, I want to use the new IPP-based api.

Could anyone suggest what I need to use in above code?
