NAME

       buffer_getline_sa - read line from buffer

SYNTAX

       #include <libowfat/stralloc.h>
       #include <libowfat/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).
