Detailed Description

Function Documentation

void onion_block_clear ( onion_block b)

Discards all data on this block, and set the size to 0.

This is usefull to reuse existing blocks

const char * onion_block_data ( const onion_block b)
void onion_block_free ( onion_block bl)
void onion_block_min_maxsize ( onion_block b,
int  minsize 

Ensures the block has at least this reserved memory space.

This is usefull for some speedups, and prevent sucessive mallocs if you know beforehand the size.
