DEVFULL

Arduino library for a /dev/full stream.

Description

The experimental library implements a stream class that mimics the /dev/full device of a Linux system. You can write nothing to it as it is always full. Every read data will return the value zero, just like /dev/zero

The 0.1.0 version is a minimal implementation.

Calls to print() and println() will be split up in multiple calls to write(). This causes a return value of n x -28 ==> mostly a number in the 65xxx range

Interface

• DEVFULL() constructor, sets the timeout to zero.
• int available() always return 32767.
• int peek() always returns 0.
• int read() always returns 0.
• void flush() does nothing but keeps some compilers happy.
• size_t write(const uint8_t data) always returns -28 (ENOSPC).
• size_t write(const uint8_t *buffer, size_t size) implements print interface. Always returns -28 (ENOSPC).

Error code

value	name	description
-28	ENOSPC	No space available for writing onto the "storage device".

Operation

Use with care.

See examples.

Future

• improve documentation
• improve code
  • test different platforms.
