Reads a TLV header from a buffer (tag and length) and returns the number of bytes used by the header.
- Returns
- number of bytes used to specify tag and length (i.e. TLV size without the data part)
- Parameters
-
tlv TLV to read the header into p pointer to a buffer containing at least the header size siez of the buffer pointed to by p isBerTlv if !=0 then the TLV is supposed to be a BER-TLV object

Directly writes a TLV header (tag and length) to the given buffer.
- Returns
- 0 if ok, error code otherwise
- Parameters
-
tagType tag id tagMode bits 5, 6 and 7 of the first TLV byte (bits 6/7: class, bit 5: constructed) tagLength length of the data part introduced by the TLV header isBerTlv if !=0 then the TLV is supposed to be a BER-TLV object mbuf buffer to receive the TLV header
