Helper functions for reading and writing tagged data onto buffers.
| EVENT2_EXPORT_SYMBOL void evtag_encode_int | ( | struct evbuffer * | evbuf, | 
| ev_uint32_t | number | ||
| ) | 
Encode an integer and store it in an evbuffer.
We encode integers by nybbles; the first nibble contains the number of significant nibbles - 1; this allows us to encode up to 64-bit integers. This function is byte-order independent.
| evbuf | evbuffer to store the encoded number | 
| number | a 32-bit integer | 
| EVENT2_EXPORT_SYMBOL int evtag_unmarshal_header | ( | struct evbuffer * | evbuf, | 
| ev_uint32_t * | ptag | ||
| ) | 
Unmarshals the header and returns the length of the payload.
| evbuf | the buffer from which to unmarshal data | 
| ptag | a pointer in which the tag id is being stored |
