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 '
' 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).
