man buffer_getline () - read line from buffer
NAME
buffer_getline - read line from buffer
SYNTAX
#include <buffer.h>
int buffer_getline(buffer* b,char* x,unsigned long int len);
DESCRIPTION
buffer_getline copies data from b to x[0], x[1], ..., x[len-1] until len bytes have been copied or a new-line character ('\n') is encountered. That character is also copied.
Note that line is not 0-terminated to make reading lines with 0-bytes possible through this interface.
RETURN VALUE
Number of bytes read (without '\n'), -1 on error (setting errno).
