NAME
       buffer_getline - read line from buffer

SYNTAX
       #include <buffer.h>

       ssize_t buffer_getline(buffer* b,char* x,size_t 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).
