NAME

       buffer_get_token_sa - read token from buffer

SYNTAX

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

       int buffer_get_token_sa(buffer* b,stralloc* sa,
                           const char* charset,size_t setlen);

DESCRIPTION

       buffer_get_token_sa  appends  data from the b to sa until one of the delimiters in charset
       is found, NOT overwriting the previous content of sa.  That delimiter is also appended  to
       sa.

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

RETURN VALUE

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

RATIONALE

       buffer_get_token_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_get_token_sa again when select or poll indicate more data is available).
