u16_t pbuf_memfind ( struct pbuf *  p, const void *  mem, u16_t  mem_len, u16_t  start_offset  ) Find occurrence of mem (with length mem_len) in pbuf p, starting at offset start_offset. Parameters: p pbuf to search, maximum length is 0xFFFE since 0xFFFF is used as return value 'not found' mem search for the contents of this buffer mem_len length of 'mem' start_offset offset into p at which to start searching Returns: 0xFFFF if substr was not found in p or the index where it was found Definition at line 1117 of file pbuf.c.
