[pjsip] accessing values of parsed 'Allow' header?

Hi Anshuman,
to retrieve an 'Allow' header from rdata msg_info, try using:
  pjsip_allow_hdr *allow_hdr;
  allow_hdr = (pjsip_allow_hdr*) pjsip_msg_find_hdr(rdata->msg_info.msg,
to create an 'Allow' header, use 'pjsip_allow_hdr_create'.
That should give you access to count and value members. Hope this helps...


Hi All,
I need the results of parsed 'Allow' header i.e. names of supported methods.
I see this function parse_hdr_allow() which returns a structure of type
pjsip_allow_hdr type casted as pjsip_hdr. I fail to understand how do I
access the 'count' and 'values' members of struct pjsip_allow_hdr as type
casting to pjsip_hdr leaves no accessor to access these members ?
One way I see is to  type cast it back to pjsip_allow_hdr in my source to
retrieve the results of parsing. Is there an accessor I am missing? 
PS: absence of REFER method in 'Allow' header neccessiates our 3PCC transfer
requirement; this serves as our trigger
