This is a low-level function retained for ABI compatibility with freeradius-client and radiusclient-ng. Application code should not call it directly; build requests with rc_avpair_add() and send them with rc_auth() or rc_acct(), which handle wire encoding and decoding internally.

Decodes the attribute/value region of a received RADIUS packet (the bytes that follow the 20-byte fixed header) into a linked list of VALUE_PAIR structures. Unknown attributes are logged and skipped; they are not a hard error.

rh

a handle to parsed configuration (used for dictionary lookups).

pair

optional existing VALUE_PAIR list to append decoded attributes to; pass NULL to start a fresh list.

ptr

pointer to the start of the attribute data region.

length

number of bytes in the attribute region.

vendorspec

vendor PEN when decoding a vendor-specific sub-attribute block; pass 0 for top-level packet attributes.

head of the (possibly extended) VALUE_PAIR list, or NULL on a hard decode error (malformed length field, allocation failure).
