man buffer_put () - write binary data to buffer
NAME
buffer_put - write binary data to buffer
SYNTAX
#include <buffer.h>
int buffer_put(buffer* b,const char* x,unsigned long int len);
DESCRIPTION
buffer_put writes len bytes from x to b.
The difference to buffer_putalign is that, when there isn't enough space for new data, buffer_put calls buffer_flush before copying any data, while buffer_putalign fills all available space with data before calling buffer_flush.
RETURN VALUE
buffer_put returns 0 if everything was fine, -1 on error (setting errno).
