- * Name: readline
- *
- * readline() reads in at most one less than 'buflen' characters from
- * 'instream' and stores them into the buffer pointed to by 'buf'.
- * Characters are echoed on 'outstream'. Reading stops after an EOF or a
- * newline. If a newline is read, it is stored into the buffer. A null
- * terminator is stored after the last character in the buffer.
- *
- * This version of realine assumes that we are reading and writing to
- * a VT100 console. This will not work well if 'instream' or 'outstream'
- * corresponds to a raw byte steam.
- *
- * This function is inspired by the GNU readline but is an entirely
- * different creature.
- *
- * Input Parameters:
- * buf - The user allocated buffer to be filled.
- * buflen - the size of the buffer.
- * instream - The stream to read characters from
- * outstream - The stream to each characters to.
- *
- * Returned values:
- * On success, the (positive) number of bytes transferred is returned.
- * A length of zero would indicated an end of file condition. An failure,
- * a negated errno value is returned.
- *
