Stream class


readBytesUntil() reads characters from a stream into a buffer. The function terminates if the terminator character is detected, the determined length has been read, or it times out.

size_t readBytesUntil( char terminator, char *buffer, size_t length);

stream.readBytesUntil(terminator, buffer, length);


  • stream : an instance of a class that inherits from Stream
  • terminator : the character to search for (char)
  • buffer : pointer to the buffer to store the bytes in (char *)
  • length : the number of bytes to read (size_t)

Returns: returns the number of characters placed in the buffer (0 means no valid data found)
