#define EOF (-1)

End-of-file return value.

## NULL

#define NULL 0

Null pointer

## SEEK_CUR

#define SEEK_CUR 1

Seek relative to current position.

## Variable Documentation

## STREAM_BUF_SIZE

const uint8_t STREAM_BUF_SIZE = 64

Total size of stream buffer. The entire buffer is used for output. During input UNGETC_BUF_SIZE of this space is reserved for ungetc.

## UNGETC_BUF_SIZE

const uint8_t UNGETC_BUF_SIZE = 2

Amount of buffer allocated for ungetc during input.
