buffer_get_new_token_sa_preLibrary Functions Mabuffer_get_new_token_sa_pred(3)

NAME
       buffer_get_new_token_sa_pred - read token from buffer

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

       int buffer_get_new_token_sa_pred(buffer*	b,stralloc* sa,
			int (*predicate)(stralloc* * sa));

DESCRIPTION
       buffer_get_token_sa_pred	 copies	 data from b to	sa until predicate(sa)
       returns 1 or -1.

       If predicate returns 1 once a '\n' was read, that new-line character is
       still  appended to sa --	use stralloc_chop or stralloc_chomp to get rid
       of it.  predicate can also return 0 (indicating further	input  is  re-
       quired  to  complete the	token) or -1 (abort and	return -1; use this if
       predicate wants to enfore a maximum message size	or does	 timeout  han-
       dling or	detects	a malformed message).

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

       On success, buffer_get_new_token_sa_pred	returns	0.

       If  you	want  to  read	from a non-blocking socket, use	buffer_get_to-
       ken_sa_pred instead.
