NAME

       buffer_get_token_pred - read token from buffer

SYNTAX

       #include <buffer.h>

       ssize_t buffer_get_token_pred(buffer* b,char* x,size_t len,
                        int (*predicate)(const char* s,size_t len));

DESCRIPTION

       buffer_get_token_pred copies data from b to x[0], x[1], ..., x[len-1] until len bytes have
       been read or predicate called on the destination string returns nonzero.

       predicate can also return 0 (indicating further input is required to complete  the  token)
       or  -1  (abort and return -1; use this if predicate wants to enfore a maximum message size
       or does timeout handling or detects a malformed message).

       buffer_get_token_pred returns the number of bytes copied or -1  on  error  (setting  errno
       appropriately).
