NAME

       buffer_getline_sa - read line from buffer

SYNTAX

       #include <stralloc.h>
       #include <buffer.h>

       int buffer_getline_sa(buffer* b,stralloc* sa);

DESCRIPTION

       buffer_getline_sa  appends  data  from  the  b  to sa until a '\n' is found, NOT overwriting the previous
       content of sa.  The new-line is also appended to sa.

       If reading from the buffer or allocating memory  fails,  buffer_getline_sa  returns  -1  and  sets  errno
       appropriately.  At that point sa may be empty or it may already contain a partial token.

RETURN VALUE

       -1 on error (setting errno), 0 on EOF, 1 when successful.

RATIONALE

       buffer_getline_sa  appends instead of overwriting so it can be used on non-blocking sockets (these signal
       error and set errno to EAGAIN; in this case you can simply call buffer_getline_sa again  when  select  or
       poll indicate more data is available).
