NAME

buffer_get_token_pred - read token from buffer

SYNTAX

#include <libowfat/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).
